I use a couple of X220s as my work laptops, as I find the keyboard far superior to the X230 and all later models (it's the last classic ThinkPad keyboard prior to the chiclet designs). The hardware is still mostly sufficient for my needs (just don't run Electron apps...) and the case and the keyboard are much better than anything I could buy new these days. Apart from the displays, it feels like laptops have mostly regressed over the last decade and continue to do so at an alarming pace (just compare the T490 series to the T480, for instance).
