Am I the only person who uses Vista day in and day out and has not had a single problem with it?
Nope, one more here. Use it at work (major corporation all on Vista) and on one of the computers at home, works fine, love it!
Still use XP on other home computers, but only 'cuz I don't feel like paying for Vista licenses when XP is still working.
I would stay well clear of W7 for a good while! Even if the operating system itself is fine, I'll happily let someone else sort out how to get all the other programs I use to work properly with W7.
I think the main reason Vista has always worked great for me is I went nowhere near it for the first six months.
