I just 99% built my new PC, and all that's left is the HDD to come in the post.

Which operating system should I use? XP Pro (already have) or Vista final beta release (which can download from microsoft)?

My pros/cons are:

Vista:
Cons:
Beta; not stable. When I want to upgrade I will have to re-install everything (which means I will need to somehow backup my files).
Doesn't have drivers for everything yet.
Pros:
Looks cool
The way forward
More features
My PC is more suited to it.

XP Pro:
Cons:
It's not vista
Pros:
It's got all supported drivers, and is stable (or at least as stable as windows can be).
Best (stable) windows edition so far.
No need to download


Which is best for me?


P.S. I don't want Linux :p
