Whats an operating system supposed to do?
An operating system is supposed to provide an environment where many different kinds of software can run well.
Well, OSX is good for graphic design, but nearly all of its programs also run on Windows 7 or have comparable software also for Windows 7. Linux has a lot of great software, but just can't really compete really with the huge libraries of software for Macs and Windows.
But in terms of number of software available, Windows 7 seems to have the most. It also runs new and upcoming games, and also runs classic PC games while XP is left in the dust without DX10.
There you have it, Windows 7, which is an operating system, runs FUCKING EVERYTHING!!!!
