Think the days of Microsoft as an OS company are drawing to a close - too much history as the company that got in the way of the user. No doubt Microsoft will be around making money, but not from Windows. If Ubuntu would stop changing every five days, I don't see any reason why everyone won't just be using Ubuntu or other UNIX variant within ten years. I'm no Linux champion, I've only used Ubuntu and it's been frustrating to say the least, but it's now as easy as Windows to install and it's free. I use windows for one reason only: My wife's work PC and laptop have to have Windows and it's too much trouble to go back and forth. I even tried a virtual machine inside linux with windows for my wife but I'd forget to keep it on or the flash drive would go to the wrong OS - PITA.
When hardware comes with Linux drivers 100% of the time, Windows is doomed. I just remembered the other reason why I'm still using Windows, I can't get my ATSC tuner to work in Linux. Media center in Vista of course works out of the box as they say. And netflix, dammit, don't get me started. There is no reason to Windows!!!!
