Personally, I think Vista is bloat all around. Crappy PC's like mine ( I have integrated graphics, LOL) won't be able to run and experience the full blown vista experience (think the Aero feature). Its probably gonna have lots of security issues and bugs in the early stages of release too.
Don't get me wrong, Vista will look awesome on high-end machines but for others, they will have trouble running it.
I use XP but sometimes I use linux
.
Just my 2 cents
