Agreed. My Dell XPS 15 is running at 3840x2160. Unfortunately, there's a few quirks:

  - Wireless drivers broken in Jessio (unless you build your own kernel)
  - UI elements are EXTREMELY small (you have to set DPI before window manager starts)

Apart from that, it's an awesome machine

How well does the touchpad work under Linux? Also, how is the battery life and GPU switching? I'm currently deciding between the XPS15 and waiting for the rMBP refresh, and the XPS15 is seriously tempting.

Zero issues with the touchpad. It just works.

Battery life is awesome. I could probably go 6-7 hours, haven't tried though as I'm mostly connected.

As for graphics drivers, it's shitty at the moment. There's no native acceleration is I haven't bothered to recompile kernels as it doesn't concern me (it's a work machine).

Someone else will be getting the same machine soon, so I'll wait for him to be my guinea pig.

Sounds good! What distro are you running?
