I have been using Windows 7 for about a month now. My previous operating system was Windows XP, and I find Windows 7 far superior. It takes a little while to get used to new ways of doing things, but once this happens, most things can be achieved quickly and intuitively. I had only one problem, my old printer/scanner from my previous PC would not work under Windows 7 (this may be because it is 64bit) even though HP said it would, but I guess that's HPs fault, and not that of MS. I would highly recommend this operating system!
