Windows 7 has been freaking brilliant, so I don't know where all of the "bad ideas only copied" come from. I use both Macs and PC's at work, and I sigh relief whenever I use Windows 7 instead of the Mac OS. W7 is smarter, lighter, and far more flexible. It's also customizable, unlike the Mac OS which tells the user what it can and can't do.
Furthermore, Microsoft released their XBox 360 before the PS3 and the Wii, and they are crushing both in that market.
You people need to get off of the water-cooler, over-generalized diatribe and do a little research. Microsoft is intuitive and ahead of the game in so many respects it isn't even fair. They wouldn't have a borderline monopoly if they didn't. It's not like they were given some unfair head start and just rolled with it. No business could survive that way; no matter how big. Not only are they surviving, but they are way ahead of the others.
