I've been running Linux on the X220 (tablet) for 4+ years at this point; it's still a great machine (although I need to boot it up and clean the insides soon...), although obviously slightly dated in terms of hardware. The X260 will likely work as an exact replica, but I haven't updated to Skylake yet so it's hard to say (ISTR there being some GPU buginess with Skylake at first). Otherwise everything should work almost perfectly out of the box, in my experience, though you'll probably want to tweak your power settings. The X260 will have a far superior screen, which if you're coming from a Macbook or anything will probably be important. One of these days I'll upgrade and take my X220 down to the local hackerspace and get Coreboot put on it probably...
