The author of the article seems to be trapped in the past, with a steady fixation on the keyboard and mouse. He doesn’t seem to understand the value of a gaming controller for SteamOS. Don’t get me wrong, I like the keyboard and mouse too but there are games where a controller can provide a superior gaming experience. His comments about Linux in general are way, way off the mark and they indicate a decided lack of faith in Valve’s ability to provide drivers and peripheral support. Valve is not a stupid company, they know full well that SteamOS has to work without a lot of fiddling on the part of gamers. And I believe they are up to that challenge and then some.
