the problem for me (and people like me) is that I'm running a gaming / game dev rig. I actually need Windows as most of the games I play are windows only - plus my current rig is way more powerful than any mac I can afford. I love linux and attempted to dev my games in pygame so that I would only need Windows to play games, but this isn't a good solution either as I prefer Unity.
Guess I'll stick with 8.1 for now even though it is shit.
I have been able to put Unity on the back-shelf because it's just a hobby for me. I have been experimenting with Phaser / PIXI / P2 + ScalaJS in the meantime while I wait for the Editor to come to Linux, which will hopefully happen in the near future [1].
As for actually playing games, a surprising amount of the ones I try have been ported over to Linux already. For the rest, I use Steam Live Streaming from a Windows 7 box which works pretty well. Steam can even stream non-Steam games (blizzard ones for example). I tried using it to stream the Unity Editor, but it was just too clunky for my tastes.
Thankfully I have 2 gaming rigs, 1 outdated mac and 2 older custom rigs that are sitting around in pieces. I'm going to build and install a linux box for personal computing (all non-dev non-gaming related computer activity) and just keep it on right next to my gaming / dev rig.
