No Vista here. I'm running XP. I use WindowsBlinds to change the look. I can't stand the bright blue bar, with the green button. And then Aquadock for the... dock.
I have a friend who used Vista a few times. He didn't seem to like it very much. the interface bothered him, but in the same breath, he said it was very customizable. Music and video apparently runs very well. He didn't test out any games, but I'd imagine they run alright. Beyond that, he didn't say much about any problems.
I've been debating trying out Vista, but then I remind myself how long it took Microsoft to work out XP's many kinks. I used '98 for years after XP was released. I use Linux on my PS3, and actually I've been thinking about running that on my PC.
And hopefully your last post was directed at me...
