It would be amazing to have somebody put together a modern laptop kit build around the x220 keyboard with a modern screen. it didnt last long, but the dimpled texture on the x220 trackpad was something I really liked, and i still miss having a middle click scroll button on trackpads. it was so nice to hold down a button and put slight pressure on the trackpoint to slowly scroll a webpage.

I'm not 100% on it but I believe an ips x230 is considered the pinnacle. the x240 is slower than the x230 because it was when strong optimization for power savings started to occur.

Agreed. I had an x201 and an x250. The 250 main board eventually stopped working (I think due to flex when the laptop was picked up from one corner repeatedly -- a known issue from what I understand). My x201 still runs great (with occasional refreshes of the thermal paste). A version of the x201-x220 era machines with modern internals would be my dream machine.
