I've had RC1 running for a while now (a few months maybe). It is kind of hard to see exactly what it offers over XP. When XP came out, I installed it on my machine at the office (I think it replaced ME, a true dog) but I can't see what I'm supposed to get out of Vista that XP doesn't provide.

Am I missing something about Vista? 5 years in development seems like a long time given what I've seen. Is there a lot more under the hood that I haven't seen?
