A friend of mine own a Yoga 2 Pro. He's using Chakra Linux, and he had to go through a great deal of difficulty to adapt KDE to the HiDPI screen. He somehow managed to do it partially (like by setting font sizes to insane numbers, etc). Even still, there UI elements scattered around that still appear as though you're looking at them from space.

Neat, looks nice - thanks for the pointer! Wish they had a 15" one without the touchscreen and gimmicky yoga thing.
