I think you're really narrowing down who would be considered a gamer. All of my close friends are gamers, but I'm the only one that can build my own gaming PC without help. None of them are Slashdotters, most of them really like Macs for their simplicity & stability (it's what I run when I'm not gaming, too), none of them give a damn about open software, and while a few of them are familiar with what Linux is, not one of them uses it. I'm not trying to say any one preference is better than another, but I think your perspective is terribly skewed. Fifteen or twenty years ago, sure, most gamers were self-proclaimed geeks and would have loved to build their own PC. But today, there are many more gamers, and the old stereotypes don't hold at all. Most gamers don't care about Windows vs OS X vs Linux, they want to be able to have fun and not spend a ton of time or money trying to get to that point. Now, I've used various Linux distros in the past and I don't hate it, but it really is far more work than the average user will ever want to endure just to get it and keep it working, much more so if you build your own rig. You can say it isn't much, but I'm sure most people here are not strangers to helping family/friends set up a computer and you know it's too much for them. I'd really like to see any open OS take off and overtake Windows as well as OS X so the world can adjust to using freely available software and let that become the way of things. But realistically, it's going to take much more than game availability to make Linux appeal to the masses. And before the Android comparisons come out, the cell phone market and PC market are not the least bit related, a popular OS on one is typically not so popular on the other (Windows, I'm looking at you) even when they are almost the same.
