Is there really any reason to get vista yet? I mean, what are the real improvements, or "wow", that its got over XP?

Heck, I've just given up on windows entirely. OSX is my main environment by trade, and am starting a Slackware machine by desire to learn (and stability). I dont plan on going back to Mr. Softy, unless I see a real need.

So again, what are the reasons to get Vista, if any?
