I still need to check whether all my favourite games are supported on Linux. Also, a lot of my games are from GOG rather than Steam. And I need to choose a good distribution. My laziness and indecisiveness is holding me back.
But I really think the time is right for something better. An OS on a Linux-like foundation, with an Apple-style UI (but better, because plenty of stuff there still doesn't make sense), capable of running all games. Probably developed and polished by a big hardware manufacturer trying to eat Apple's lunch. There's System76 of course, but they're small. I want something that's for everybody. A new standard to draw everybody away from the increasing piles of crap from Apple and Microsoft.
