I'm currently tri booting arch linux, os x and windows on a retina macbook pro. I almost only use linux, support is much better than suggested here. Yes, if you expect the latest build of Ubuntu to just work you're going to be disappointed. The trackpad works excellently, equivalent to os x (with mtrack), as does wifi. Graphics are fine with the nvidia binary, which offers better performance than nouveau anyways. On that note, there is progress with getting nouveau to work. Just a few days ago a bug was fixed in the i915 driver, and intel graphics work now. It is true though that Optimus support is bad on linux, and probably will be for a while. That said I'm at 86% battery, and I have about 3.5 hours left. Its pretty easy in linux to change the font settings for applications, having the 2880 resolution with a sane font size is really great. Also switching between the os's is really really fast, around 30 seconds. Probably in a month or two the majority of hardware will work without development packages or other modifications on an arch install. Until then, installation is tricky, I wouldn't suggest it unless you already know linux pretty well.
