I think there is no future in Linux and Gaming. It will be still a OS which u can work with and also better secured than MS Windows but for gaming i think Windows will still be the best one on market.

How can you say that? Linux can do most things that "the operating system that shall not be named" and is not anywhere neer its peek. As long as there are gamers out there who are any good at making things, there will always be a way for linux to be gamed on. An operating system dosnt NEED to be MADE with gaming in mind but there are programs such as wine out there to make it easyer to game. Just because "The OS" has parts designed to game dosnt make it better.
Besides, some people refuse to use windows but want to game, Something will always be in place for thows of us who refuse to use "it" for our own reasons.
