My simpleton argument: 1. Linux users are much nerdier. 2. Nerds play more video games. Some more speculations: * Windows appeals to people who want to be in majority. This makes them feel comfortable. Of course, it has a stronghold in business world too. * Mac devices are seen as status symbol. It's elegant, 'just works', 'stylish' 'gorgeous'. And they don't use it /despite/ highish cost - they use it in part /because/ it's expensive. You don't actually need to do anything with it, it's enough others see you have it. * Linux appeals to people who like to brag how much they can do. Tweakers, tinkerers.
