Any way you go, it is hard to see why Windows has the dominance it does, and Windows 8 only goes to prove that it shouldn't realistically be so ubiquitous.

People don't use Macs as much because they have fewer games and because they're more expensive for the same processing power.

People don't use Linux as much because, again there are *MUCH* fewer games, the number of flavors is confusing, and (likely depending more or less on the flavor), it requires a certain understanding about command line usage.

Windows has certain proprietary advantages over Linux; and it has a smaller price point and more power user abilities than Mac OS.

People say that Mac OS is better because there are no viruses, but the reason why is because the market share is so small. If the market share for Mac in any way rivaled that of Windows, you can bet your ass there would indeed be viruses.
