Yeah, I do. Just wanted to try it a couple of years ago. Honestly -- not worth it (on Linux HiDPI is not there where I wanted it to be, plus with my love of bitmap fonts, it can be hard), especially in a heavily shortcut-powered WM (I use Fluxbox and bspwm occasionally). But that's just me.

My next workhorse will still be X1 nextgen, but with regular 1080p resolution and matte screen. Much much better. Like my Zenbook at home -- which is ideal for me, but less powerful for work-related tasks.
