Pepperidge Farms, oops I mean Framework, remembers.

Bought this Framework 16 laptop less than a year ago so I haven't upgraded anything yet. But if I decide I want a GPU (I don't play games on this laptop so I bought it GPU-less) I can add one. If they come out with a new motherboard that I decide is worth buying, I can swap it out and keep the rest of the laptop. And I can customize all six of the side ports at any time; they're hot-swappable. Currently I have three USB-C slots, one USB-A for when I need a thumbdrive, one HDMI, and one SD card reader slot. I bought a second USB-A slot and an Ethernet slot, so if I need two USB-A ports or if I need to plug into Ethernet, I can just slide the physical locking tab on the appropriate side of the laptop, slide out one of the slots, and slide in the Ethernet or USB-A slot. Then relock the tab so the expansion slot fillers are physically held in place and I can carry on. No rebooting needed, but now I have two USB-C ports and two USB-A. Or three USB-C, no USB-A, and one Ethernet. Whatever configuration I need at the moment.

It's great. I currently don't have any plans to buy a new laptop in the near future (my wife's laptop is just two years old and has plenty of life left in it), but next time I need a new laptop, I plan to buy a Framework again.

P.S. No affiliation with Framework, just a customer.
