The recent news that SteamOS may soon be shipped with third-party devices could be particularly important for Linux gaming on desktops.
Even gamers nexus' Steve today said that they're about to start doing Linux games performance testing soon. It's happening, y'all, the year of the Linux desktop is upon us. ᕕ(ᐛ)ᕗ
Edit: just wanted to clarify that Steve from GN didn't precisely say they're starting to test soon, he said they will start WHEN the steam OS releases and is adopted. Sorry about that.
Once the userbase becomes bigger, those folks will move over. Capitalist will follow the money, they don't care what OS it is as long as they can make their lords shareholders happy.
It already started with a lot of gaming communities, but most of what I use is already in Linux so no Biggie for me, productive apps being moved is likely very far into the future
