It's not that Vista is a bad choice for an OS, far from it, on a new machine it's a better choice and I personally am quite happy with my Vista experience, but I can't ever see a reason to upgrade from XP.
Then you haven't looked into it. Unsurprisingly, Microsoft made a *lot* of changes over it's 5 year development span, and anyone that does more than scratch the surface can see that. There's far more to Vista than just Aero (or 'oohhhhh, purdy!').
