I've been running Vista since launch day back at the end of January.
I have had a few problems with crashes but not many. I love the interface and some of the MS programs that come with it (ie. Windows Picture Gallery, Windows Movie Maker, Mah Jong!!).
After using Vista Premium for awhile, going back to XP feels very dull and boring.
However, the simple fact is that there is nothing wrong with XP, especially since SP2, and while Vista has proven to be very stable for me, XP still wins on that front for the time being.
My advice, and I know it is late in coming, is to stick with XP if it is working well for you. If you would like a slicker interface with some extra bells and whistles, by all means install Vista and go for the ride.
Just make sure that the software and hardware you are using is Vista compatible, though I haven't had any problems with my printer, mouse, digital camera or camcorder.
Has anyone had any experience running Vista that was NOT bogged down by all the manufacturer's added software?
Yes and it is faster than XP, though I have an AMD X2 4600+ and 2 gigs of RAM.
