Personally I think beyond T450 generation, i.e. over 10 years old systems, you are starting to make pretty severe compromises. T440 generation had really bad Trackpoint setup, and older hardware starts to lose features. Random stuff that T450 has that T400 doesn't
* USB3
* Up to 32 GB of RAM (vs max 8 GB for T400)
* M.2 slot (for SSD), 6 Gb/s SATA (vs 1.5 Gb/s on T400)
* x86-64-v3 (AVX2 etc) and OpenGL 4.6
* Dual-band AC wifi and BT4.0 (optional 4G LTE WWAN)
* DisplayPort with 4k@60Hz output
* Slightly larger screen estate (1600x900 vs 1440x900), with FHD 1080p display option
* Dramatically better battery life
* Backlit keyboard
Many of these are not merely nice to have but also ensure longevity by being compatible with lot of other modern stuff. On the other hand I do believe that T450 generation device might remain viable daily driver for a long while still. From the specs the biggest obvious shortcoming to me is the lack of USB-C, especially USB-C charging. But besides that, it seems pretty usable system.
For reference, I have old X240 that I still occasionally use.
The tightness of hardware integration isn't a bug, it's genuinely a feature; In fact, it's the defining feature that makes Apple hardware great. Socketed RAM, CPU, and Storage just weren't worth the tradeoffs, namely size, weight, cost, and performance. Including those modular interfaces just wasn't worth it when the internal interfaces would be obsolete within 5 years, and the average user was replacing sub-components 0 times over the life of the device.
The user being able to swap parts easily is _neat_ but it's just not an required feature, any more than the user of a car being able to easily hot-swap the engine. The right level of integration provides a tradeoff the maximizes reliability, cost, performance, and repair. A professional can still replace almost any component of a modern laptop, with a few thousand $ of specialized tools, and the battery, the only component with a fixed lifetime, can be easily replaced at home.
I really hope Framework can continue to develop hardware with documented repairability, without falling for the myth that tight integration and quality are mutually exclusive.
> A [macbook] battery replacement involves carefully prying out a glued component.
Can't speak to every model, but it's not always like this. I just swapped the battery on my 2020 M1 Macbook Air, and it's much easier now. The battery is glued to a metal tray that unscrews and lifts out of the laptop. It is discarded with the old battery. The tray is also held down with pull-tab adhesive strips, but they are trivial to remove - similar to what "command hooks" have.
https://www.ifixit.com/Guide/MacBook+Air+13-Inch+Late+2020+B...
I've also done a battery swap on a 2015 Macbook Pro 15" - much harder. Each individual battery cell is glued directly to the chassis, and removing each one involves a lot of prying and praying it doesn't puncture or decide to detonate.
Back to the macbook air, I've also replaced the screen and USB-C ports. It's not that bad.
It's not a classic thinkpad, but my thinkpad from 7 years ago is still going strong.
Recently I decided to do a service on it for the first time, and I was absolutely stunned by how little dust had built up in the CPU fan and the interior in general, after 7 years of usage, often sitting on top of a couch or bed, near my long-haired Norwegian forest cat Rufus. All it needed was a litle puff of computer duster and it was good as new. That's very good design of the air intakes and is a huge factor in the machine's longevity.
I did computer repair professionally for a while, and one of the most common causes of irreparable death I saw in laptops was massive dust buildup in cpu fans and consequent heat damage to surrounding components. I'd sometimes see this in 2-3 year old laptops even.
Funny to think that something as simple as the shape of an air intake opening can have such a profound impact on the lifetime of a device.
The other thing that Thinkpads are unrivaled at is protection for the display. People like to say macbooks are sturdy, but they are quite prone to cracked displays because of Apple's obsession with smaller bezels. The thinkpad ofc has t34 style angled armor for its display. Can't remember ever seeing a Thinkpad with a cracked display. And I carry my Thinkpad around in just a backpack with no sleeve, often the Thinkpad is the only thing in there, and it regularly impacts the floor when the(thin-bottomed) backpack is put down while sitting down on the bus or getting home.
Having run some hardware for about 20 years (recently deceased), the problem that eventually happens is that newer OSes drop support for old hardware. If you hit some weird bug on your setup on a new OS release, there won't be anyone to help you fix it[1]. So then you're stuck on an old OS. In time, that means you can't run the latest userland software either, which relies on more modern OS features (eg: your Firefox will get increasingly out-of-date). That means the set of things you can do will eventually narrow and narrow.
If you're only running programs that you have full control of, and can compile/fix locally, or where receiving security fixes &etc. don't matter, then you're good. But things are a bit more interconnected, these days.
I do still enjoy running my hardware into the ground rather than tossing out perfectly good components every few years though (:
[1] In my case, the boot loader stopped working for my hardware on FreeBSD 11.4
My x220 has traveled around the world multiple times. It's been through dozens of airport scanners, dropped multiple times, and shared a few cups of coffee with me by accident. It just keeps on kicking. My x220 running Debian is actually quicker and more responsive than my friend's modern Lenovo running Windows. I'd be tempted to upgrade to a lighter and thinner laptop, but I'm too attached to the keyboard.
T480 (non-s)
- Love the dual batteries (one swappable) unavailable on Apple-design infested T490
- Retrofitted with magnesium top case and bezel mod
- 5 extended 72 Whr batteries with a third-party external charger from some dude in the UK
- Upgraded to fastest processor and discrete GPU (slow on its own but I use a Razer Core X eGPU with an Nvidia RTX 3070 Ti, and can run basically any game on Steam.)
- 32 GiB of RAM
- WiFi 6e Intel AX210 (looking at WiFi 7 using the AMD-compatible Broadcom FastConnect 7800 / QCNCM865 that I run on my AMD 7900 Asrock DeskMini X600 electronic lab Windows-only things box that I'm typing on right now).
- Bought OE replacement most likely to fail: keyboards, pointing stick (and tips), trackpad assembly, and fans (I think I bought 6). Any loose USB, etc. connectors I can resolder myself.
- I might have a slight mainboard problem because I'm constantly running ThrottleStop to get higher, sustained Tdp with SpeedFan sending fans manually to full blast or otherwise the max freq randomly drops to painfully-slow 900 MHz max non-deterministically.
I booted up my Thinkpad 760 XL from 1997 recently and let it run for a couple days. My WinZip was more than 9000 days past expiration, and it counted up one by one, the number just spinning ever upward for the better part of half an hour. 2 of the 3 batteries I had for it still charged to above 90% and drained at the normal rate, so I could still run it unplugged for around 6 hours. The batteries were modular, so you could have a cdrom, floppy, or battery in the first bay and a battery in the second bay. I normally ran it with 2 batteries and an external pcmcia cdrom that ran on double-a's. For a 28 year old laptop, it was still incredibly usable.
I run NixOS on a coreboot-ed T420 and I absolutely love everything on the outside, but it really shows its age when compared to the display on my Macbook or it comes to running heavier software ie. rust-analyzer, Chrome, or Nix builds.
If Lenovo were to release a modern T420-like, with identical chassis, battery system and similar IO port variety, but a modern display, modern internals (replaceable SSD! soldered RAM at least has a case for performance) and a modern camera, cash would evaporate out of my wallet.
I remember there was a person [1] modding T60/T61s into "T700"s with 11th gen Intel chips. Unfortunately it looks like the project's been quiet since 2022. Hopefully there'll be more who try.
My old ThinkPad X220 is the laptop I miss the most. My employer at the time replaced laptops after 4 years and sent the old ones to be destroyed for compliance reasons. I begged them to just destroy the SSD and let me keep the laptop, but "company policy..." In a sensible world I would still have that machine.
I love these old ThinkPads. I refurbish and sell them all the time. Just moments before writing this, I finished fixing up a T580; earlier today I did a heatsink replacement on a W510 which is going strong with an SSD and 20GB RAM.
The older they are, the better they are, but even the modern ones are still pretty good. Like the OP mentions, the market for parts is strong and it's easy to get what you need. Then when you go to sell them, they sell for a good amount. That W510 is worth at least $100 in its current condition.
I have an IBM T42, but I have the supervisor password set that I have long forgotten. I know about ways to clear the password (if they indeed work) but I have not gotten around it. If anyone knows a solution that does work, feel free to share.
It is in a mint condition, not a single scratch, and I don't want to throw it out for sure. I have an old OpenBSD on it, it is perfect for some light C coding using mg. :)
I have a T450 with a issue that I haven’t been able to figure out for years: When I shut the lid, the screen will shut off, and when I open the lid again, I can hear the fans spinning and I know the laptop is on, but the screen WILL NOT TURN BACK ON. I have to hold the power button to force power off and then start it up again.
Issue happens in Windows and Linux. I tried disabling the sleep enhancement feature in the BIOS (can’t remember what it’s called).
So it’s just sitting on my bookshelf. Sad because it works great, but you just can’t close the lid.
I still use my T470S as a Ubuntu 22.04 development machine. I bought it from my pre-pre-company as a used one back in 2022 and it is a fantastic laptop for personal projects. The only update I did was a 16GB RAM to up the memory to 20GB. I also bought a new battery as one of the two was dead.
I wish the graphic driver could be better as playing Youtube videos constantly crashes Firefox on Ubuntu. Other than that I have nothing to complain. I have been using it for 3+ years with zero maintenance (I didn't even bother to clean the fan) and it never failed me.
I have a second "new" Dell workstation laptop standing by just in case it breaks down. But it is a Windows machine with 32GB of memory, so I'll probably use WSL2 instead.
Well, next to a x220 from 2012, sits my eee-pc 701, from 2008. With no-moving-parts-inside, and "huge" soldered 4Gb ssdisk with arch-32bit. Been around the world (literally), a few times. The touchpad buttons started falling few years ago. i keep putting them back. Rarely used nowadays - but battery still holds about hour+ .. Well made tiny machine.
i guess i am a hoarder? Hate to throw away useful working things..
There's a fallacy often repeated for computers: "It's lasted a long time so it's going to keep lasting a long time." The thing is, failure of computer hardware is often due to manufacturing flaws. There's many that could have flaws, and they're subject to (varying) environmental stresses (both at build time at run time), so there's many failure modes.
It's difficult to know exactly when a server might fail. It might be within 1 month of its build, it might be 50 years. But what's clear is that failure isn't less likely as the machine gets older, it's more likely. There are outliers, but they;re rare. The failure modes for these things are well recorded, and the whole thing is designed to fail within a certain number of hours (if it's not the hard drive, it's the fan, the cpu, the memory, the capacitors, the solder joints, etc). It doesn't get better as it ages.
But environmental stress is often a predictor of how long it lives. If the machine is cooled properly, in a low-humidity environment, is jostled less, run at low-capacity (fans not running as hard, temperature not as high, disks not written to as much, etc), then it lives longer. So you can decrease the probability of failure, and it may live longer. But it also might drop dead tomorrow, because again there may be manufacturing flaws.
If given the choice, I wouldn't buy an old machine, because I don't know what kind of stress it's had, and the math is stacked against it.
> MacBooks are not modular, completely proprietary, and have a perishability built into them.
I'm ok with this... maybe I'm odd? I view my laptops like I view my cars: I expect them to be replaced after a period of time. I'm NOT trying to maintain my old 2002 Honda Civic, and I'm NOT trying to maintain my older Macbooks. Once they leave Apple Care, I expect maybe another 12 to 18 months out of them, and then I move on.
Where does one find a replacement battery for a thinkpad that doesn't die after 6 months?
I spent $100 on what I thought was a legit and reputable local middleman for laptop batteries (of course they just buy from China), but even then first battery was half dead on arrival, and second free replacement was dead in around just under a year with rapid capacity decline after 6 months.
Another x220 club member reporting in. My employer was getting rid of old machines a few years back, I got it for £20. The only work it needed was to resolder the left speaker, I think it already had an SSD in it.
It weighs less than 2kg and is perfect for light duties.
Bought an X220 years back and it unintentionally became my main laptop for a few years. Sold it on in much worse condition (I kept the keyboard) at a profit and got an i7 X230T instead, which has also somehow gone up in price since.
the X230 didn't last as long, the efficiencies of the M1 macbooks were too good to ignore. Gave it to my mother since because she wanted "an old laptop that just works"
I'm running a Lenovo Thinkpad, X1 Carbon from a year or so ago and it is, by far, the best Linux Laptop I've ever owned.
Unlike the 4 or so Dell (and Asus) laptops (that came with Linux preinstalled) that preceded this one, it can simultaneously support:
* Bluetooth. Yay!
* Wifi. Yay!
* Sleeps when the lid closes. Yay!
* Stays asleep when in my bag. Yay!
It's also reasonably fast and decently capable, but the not-trying-to-commit-heat-death-suicide-in-my-bag and supporting BOTH Wifi AND Bluetooth at the same time are really the biggest features.
I replaced my 2019 Macbook Pro 13" i5 16gb/256gb, with an M4 Pro 48gb/1TB 16". It just wasn't worth it anymore, it would stall opening some large files, the fans would spin up for inexplicable reasons, the screen was mid... it was just barely serviceable for my needs and wasn't worth being so frugal about anymore. Yes technically I could use something from the 80s to write text files if I wanted to most of the time, and I'm somewhat anxious about the possibility that some component soldered to the MB will short one day and kill my SSD, but it's still quite a worthwhile upgrade.
I too maintain an older thinkpad! i want to say T430 so probably not as old, maybe got in 2012 or so? In any case, I have replaced: the screen, the battery, the power button (3D printed), the hard drive, the RAM, and the entire internal fan /cooling structure, and probably some more things I've forgotten. Why? Well it's all been over the years. But 1) because you can! like this post describes. Also: it's been nice to have a windows system around that I can remote into for certain tasks that are difficult or impossible on linux, like using the adobe suite. The last time something broke (the fan) I looked up how much a used T430 costs on ebay (~$40-$50) and buying a new fan was still cheaper. So I fixed it. It's been like that every time and it's still here.
In September of 2012, I bought a T430 from Lenovo. I loved that thing! Covered it with stickers, even upgraded it as the years went on.
Eventually, it had a Core i7-3820QM with 16GB RAM, 1080p screen (with an adapter), SSDs (plural, I put one in the UltraBay)... I installed Coreboot with Tianocore, upgraded the WiFi card... I even modded in the keyboard from a T420.
In June of 2022, 10 years later, I bought an X270 off eBay. I could still use the T430, it was just starting to feel sluggish... I just felt like I needed a new laptop. I'm very happy with the X270 and I hope to use it as long as possible.
It was also fun to start covering it with stickers all over again!
I still have the T430, it's just not being used and it's sitting in a storage locker (with my vintage computer collection).
I daily use FreeBSD on 2011 (14 years old now) legendary ThinkPad W520.
Details here:
- https://vermaden.wordpress.com/2022/04/14/freebsd-13-1-on-th...
Article is about FreeBSD 13.1 - but as time passed I followed all new versions and its at 14.2 now.
Config did not changed - still running strong.
I just finished completely rebuilding a 2008 and 2010 macbook pro. The older ones are quite serviceable. This round, the speaker surrounds had cracked causing buzzing audio or no audio. I managed to ebay brand new speaker replacements and got them installed. I cleaned everything and re-pasted the CPU/GPU while I was in there as well. They are on El Capitan and High Sierra, but can be patched to be upgraded to Mojave if I wish. Currently running a LTS version of Firefox as my browser.
I appreciate the author going over the "strategic value" of both, but it seems like a desktop would fulfill the same purpose (modularity, repairability, linux) as the ThinkPad? Or, considering he obviously requires a more powerful machine than the T400 for LLMs and video editing: the MacBook? What is the point of two laptops in this case?
I’ve been using my 10-year-old ThinkPad X250 and a decade-old workstation without feeling any need to upgrade. However, the possibility of running powerful local LLMs that require a lot of GPU or unified memory has finally increased my interest. It's my impression that laptops likely won’t see the major leap required in that area to run truely large LLMs for another 5–10 years, but I expect workstation capabilities to advance more rapidly, meaning I may upgrade in the next 1–3 years.
My current workstation setup includes 22cores/44threads decade old xeon plus four decade old Titan X GPUs with a total of 48GB VRAM, which is enough to run a decent local AI model, but I’m finally wanting more capacity. I haven’t been this interested to upgrade in a decade. NVIDIA’s new DGX-class offerings might convince me, depending on pricing and supply, although waiting a few more years to let things stabilize could be what I do. Still, it’s an exciting time for hardware, especially now that there’s a tangible reason to invest in more power for local AI.
I’m currently coding a Flutter app on a 15-year-old Dell desktop, running Linux. The experience is great. I’m running latest versions of VS Code, Flutter, you name it. It’s nice and snappy and a joy to use. I’ve upgraded RAM, SSDs, GPU over the years to keep it somewhat up to date. Eventually I’m going to have to cave in and buy a Mac so that I can publish my app for iOS. I’ve been loathe to do it though and I’ve been putting it off. This article is a great explanation of why I’ve been so loathe. It articulates reasons that were semi-subconscious for me.
There’s nothing out there that matches the bold business look and feel of old thinkpads, my personal favorite being the x61. These machines are so well-built and beautiful, and I respect and understand the decision to try and keep them running. But I would respect a restomod more =)
I still primarily use Thinkpads for all these reasons. One incident with fluids and a $3k Apple machine is e-waste. I had young kids, it was inevitable.
Instead, refurbished Thinkpads are still coming off leases. Available for a 250-700 refurbished. Bench repairable. I keep good backups. If something incredible happens and I can’t fix it I can get a new one same day and be back on my feet.
And I like the aesthetic. They’re built to be durable. The chassis has fluid channels. The parts are replaceable. They’re black, unassuming, and utilitarian.
It is getting harder to keep the latest versions of some distros running on them. Software continues to expand like a gas and developers don’t seem to run their stuff on anything but the latest spec hardware. But there are distros out there where folks take care to keep things minimal and fast.
These are still powerful machines. Not editing 4K video on them. But they’re dang useful for coding, writing, and day to day things I do.
So if I was looking for an older Thinkpad to throw something XFCE flavored onto, what are some model numbers to look for? I'm basically just looking to do word processing/browsing, but I assume I'll have to jack up the ram, maybe replace the main drive with an SSD...
My T420 has a couple of upgrades: Memory (16GB) and SSD (250GB). That's it. It's bone stock otherwise. When my buddy's laptop screen cracked, we had a hard time finding a new one. He took my T420 to work every day for a few months, and it came back to me more banged up than when it left. It's fine. And it did the job admirably.
I need to do some automotive tuning/testing and guess what, the T420 is where its at for that, too. It's no longer good as a daily driver, but it'll do everything else just fine.
(Joke)
What do you mean a Thinkpad is repairable? If a chip dies, you have to go out and buy a new chip!
Whatever happened to the days where you could just wire in a new transistor yourself?
(/Joke)
Jokes aside, my point is that this article is splitting hairs about where repairability and integration lies. It's not worth opening up a failing RAM module to find the microscopic broken transistor. For many of us, it's not worth repairing an old laptop, but instead we'd rather have the advantages of everything soldered to the mainboard.
(Although I will admit to repairing an old Mac laptop. The fans started to squeak, so I changed them.)
I've been on a non stop thinkpad streak since 2005 or so. T42 (IBM), X200, X230 and now X1 carbon.
I used a thinkpad X200 back in 2014 or so and it got completely destroyed due to a spill. I replaced the memory, keyboard etc. but was unable to get it to work again. Also, the monitor had developed a few dead scanlines so I decided to buy another one. This was my primary work machine so I needed something quickly. I got another x230 off ebay. It was a piece used for demos at shows so it was refurbished. Threw Debian onto it and started work 2014. I used it straight till 2022 or so. It was my primary machine. I replaced the battery, added RAM. Then the fan got damaged and the front plastic plating got cracked so it was no longer presentable. I bought an X1 carbon but gave the laptop to my son. We bought a fan, thermal paste and some plastic parts for the casing, a new battery etc., watched a few youtube videos and fixed it up. It's still running and they play casual games on it. It's now atleast 10 years old and still going strong.
It's a very strong machine with great longevity. Though I feel that the newer ones are not as good as the old and the X1 is definitely less repairable than its older cousins.
Having used old thinkpads I just don't really understand the appeal, especially with how poor old LCDs look. The trackpads are tiny, the battery life is abysmal, they're heavy and like an inch thick.
I have a Lenovo ThinkPad T61 that I absolutely LOVE! It is running the latest Xubuntu (24.04) with no problems. I have maxed out the RAM, installed an SSD, and even upgraded the CPU. I like it even more than my Dell E5440. No, I cannot play Minecraft on it that well, but it is a SOLID laptop and it feels good to hold and type on.
Still have a T420 I keep in my toolbox in the garage. Use it to watch videos when I'm working on my bike or car. It's covered in grease and oil. Sits out there through summer/winter, high humidity, etc yet always boots up when I plug it in.
I got an x220 jumping onto the hype but it was too small and too slow to use. Even though I'd maxed out the RAM, replaced the solder paste and was running a lightweight i3 environment.
I've only ever personally owned second hand Thinkpads and they're so great. But you should get the newest, reasonably priced one you can. There are so many affordable T480s/T470s out there or even the newer T14 models. They're still very serviceable and many still allow expansion with unsoldered RAM.
I just replaced the seat back on my 2005 Aeron chair as well. Feels good to take an old thing and make it feel new. These kinds of opportunities need to be designed into products, but maybe even more importantly, people need to value those design choices so much that they'll pay more for these types of things.
I am daily driving ThinkPad T14s Gen3 AMD that I bought off Ebay a year ago. It was opened but new with warranty until 2026 and I only paid for 600 British pounds for it. It is not as repairable as their other models but it has a premium quality build, a modern CPU and full Linux compatibility. It is also the first generation of T14 when they returned 16:10 screens, this aspect ratio is a must for coding. ThinkPads are seriously underrated.
I used my T420 up till 2021.
I upgraded the screen to a 1920x1080 IPS panel.
SSD.
I have a full-fledged workstation for anything that needs heavy lifting and I primarily used the laptop as a device to remote into my workstation.
It was perfectly fine for standard web browsing and youtube.
I've been pondering the same thought recently but applied to analog cameras. Analog cameras have evolved over time, approximately according to the following:
- fully mechanical
- mechanical shutter with light meter
- electronic control of shutter, mechanical advance
- fully electronic shutter and advance
Broadly, what I'm finding after digging in to restoring some cameras is that most of the cameras from the first stage can still be fixed and made to perform close to when they were new. The second still work, but the light meter can die (simpler light meters may be repairable, later ones not so much). The third and fourth stages - once they die, there's no repairing them. And when you look at digital cameras, there'll be very, very few of these that last long into the future.
This bears out the 'Lindy Effect' mentioned in the article.
I have bought laptop in 2013 asus rog gaming one i suppose before it as well. Still rocking with i7. But it can still work with windows 11 but tpm makes it useless. So I have tried windows 11 but it hangs a bit linux runs smoothly.
I bought a x220 about 10 years ago, and then a x230 a couple years ago. I also have a M1 Pro 16 inch but sometimes I enjoy working with the Thinkpads more than that. I really wish we could get a modern system that was build like the old Thinkpads. Especially regarding overall Size, repairability, connectivity and Keyboard.
I have a x220 with an adjustable screen. I broke the screen and the battery can't hold a charge. The power button cover is messed up. No hard drive cover. Last I looked up the screen install was complicated and expensive. Probably take over $200 I paid on eBay for it. It has an unlocked bios though which I've read is rare.
As an E15 Gen 2 owner, I'm in awe of you wizards keeping these ancient ThinkPads alive - my modern entry-level machine suddenly feels inadequate despite having 4x the processing power!
A 17 year old ThinkPad is going to have extremely limited utility for today's applications. You can browse the web****, sure. You can replace parts, yes. But it still performs like dogshit for today's applications.
That said, I maintain a G4 Cube running an outdated OS to play Sim City and Sim Tower. And it's "upgraded" as much as possible.

Want a real solution to electronic waste?
The EU should mandate 10-year warranties for higher-end consumer electronics and durable goods.
This could work on a sliding scale: less expensive items get shorter warranties (but never below the current 2-year minimum), while pricier products require longer coverage periods.
Such legislation would:
1. End the exploitation of workers in sweatshops producing deliberately short-lived products
2. Discourage planned obsolescence and reduce manufacturing waste
3. Significantly decrease the climate impact of consumer electronics
4. Create genuine incentives for a Circular Economy where durable products like quality ThinkPads become standard rather than exceptions
By requiring products to last, we'd not only protect consumers and the Environment, but also the vulnerable workers currently trapped and exploited in sweatshops designed to produce disposable goods.
I wish that Framework could attain the same lofty levels of "second hand market success" that ThinkPads enjoy. A lot of the "Thinkpad fans" I've talked to genuinely want them, or respect them for similar reasons they enjoy the ThinkPad legacy.
ThinkPads are durable but every day they get older, slower and more difficult to source parts for as collectors entrench themselves and the requirements of operating systems (and the "modern web") worsen
Framework laptops are wonderful, modern and (arguably?) cheaper to own in the long-term thanks to being able to replace components, particularly the entire mainboard as time progresses.
*But* they're a tiny boutique manufacturer. Their barrier to entry is that of a pretty hefty modern laptop, versus buying a T420 for practically pennies and performing all kinds of aftermarket "mods" to it. 51nb's "FrankenPads" especially breathe incredible new life into old IBM and Lenovo stock.
Combine this with the fact that being the "defacto business laptop" for nearly three decades (along with perhaps Dell) means there's enough Thinkpads on Earth to probably stretch end-to-end around the moon and back
