Vista users, how is it?

I'm sure some of you are already using Vista, so I wanted to know,  how is it?  Is it worth it right now, or should I wait for the bugs to be worked out?

Well I do plan on using my new computer for a lot of graphical work; photoshop, illustrator, flash, etc.

If I were using vista with a gig of quality RAM (and high end video card, and dual core processer w/4mb L2 cashe) would I notice any glaring problems?
