Normally with me, if something can go wrong it will go wrong!
So how surprised was i when on installing the RTM version of Vista (after being one of the beta testers) that it all worked fine with no problems, at great speed and with no compatibility problems (except for my creative webcam but who relies on Creative to supply good drivers for anything?).
I've been running it since release date and haven't had to re-install or even clean up the install, something i used to have to do with XP on a almost bi-monthly basis.
I was stuck using XP a few weeks ago while away and to say it felt clunky and amateurish is an understatement.
I'll also like to say that i find the IIS7 interface far easier and my work flow has rocketed

I guess at the end of the day it's a personal choice just like everything.
