I love Windows 7 (hate Windows 8, but that's a different story)
I see Windows 7 as the next XP. Windows Vista and Windows 8 are crap. The only thing they got right on Windows 8 is the copy/moving feature. Using Windows XP today is a bit like using Windows 3.1 in 2000. If it serves your needs then fine, but it's time to let go and move on to something more modern!
