Yeah, I had a failed attempt at going pure linux (Ubuntu) a few months back as the applications that I use are almost all freeware anyhow and most have either linux versions or feature-parity equivalents. I spent a few hours trying to get Guild Wars 2 to run under WINE and eventually realized that the launcher
hates Unity, threw my hands-up, put Windows 8.1 back on and then proceeded to not play Guild Wars 2 anyhow.

(it only ran at like 8fps with MATE installed so that put the nail in that coffin)
I'm going to give it another go with SteamOS though as I've already seen the installer screens which indicate that there
is an easily accessible 'Linux Desktop' so after that it's just a matter of forcing myself to only purchase games with native linux support from here on out. (a lot of the indie stuff I mostly play already supports linux so there's that)
It's gonna be tough but I'd at least like to give it an honest shot this time of say 3 months without anything Windows/WINE. Native linux or you're off my wishlist kinda thing.
edit: Getting close. There's now a SteamOS directory in the apt repo.
http://repo.steamstatic.com/
edit2: There's now a
download folder with this file:
http://repo.steamstatic.com/download/SteamOSInstaller.zip
(960mbs...this looks like it folks)
edit3:
http://store.steampowered.com/steamos/beta/ now takes you to the storefront instead of a 404 so the proper page should be up any minute now.
edit4: Be sure to use a download manager as the speeds are all over the place with server errors and drops etc.
