I've been on Vista, and only using Vista since about October 06 (beta version), i'm now running vista business on my main pc (apprently this is the only version you can connect to domains on, plus i got the copy free from work LOL), and vista premium on my laptop.
No probs at all, no crashing, no driver problems, no software problems.
I think the people who are having problems are either using older hardware, or just dont know what there doing.
all IMO of course.
