Better Than XP
I could keep bringing up examples, but I think you get the idea. At the UI level, the human level, Vista is different far more often than it is better. Even so, I think it must be said that Vista is indeed an improvement on Windows XP. Honestly, I think that's the only metric that really counts when you think about it: Is Vista better enough than XP to be worth the upgrade? I'll say yes. This may be more of a comment on how bad XP really is more than how good Vista is.
