I use Linux at work and am a big fan of it. It is terrible when it comes to hardware compatibility, however. In the old days the adoption of video tape came only when there was demand. In that case the demand was driven by pornography. What will push users to Linux will be the cost savings of the operating system and great games which will drive in the hardware support. However, the chick and egg situation of which comes first the game or the hardware support is being settled by Valve which wants to be free of the costs associated with Windows. They are creating SteamOS and are working with hardware vendors to finally get decent driver support. This is fantastic. I love my Windows 8.1 PC I built myself but I will gladly switch to Linux if it can support the games I love.
We are still ages away from a Utopian gaming environment on Linux but this is where it is going to start.
