I have a lenovo x131e I still use as a daily driver, It's getting up there in age, but I will be very sad when it dies, mainly because of it's perfect openbsd compatibility, sleep/resume works flawlessly, and it has three physical trackpad/trackpoint buttons for that sublime X11 experience.
I have one of these too, and I honestly can't fault it. Runs Arch + i3 and they're very cheap in Australia since the education department handed them out in schools.
Once things get too sluggish for me I'll see what hardware hacks I can do to bring it back (I also wouldn't mind swapping the charging port to USB-C), but until then it works well for my needs.
