I agree, Win 7 is lots lots lots better than XP ever was... and I consider myself as someone who always said I would not move from XP! It's reliable, stable and a damn sight faster ime. You still have until 900+ days for XP support so enjoy whilst it lasts!
What? Only 900+ days before XP becomes...slightly more officially another of Microsoft's unwanted children which nonetheless continues to function? WHATEVER SHALL I DO.
In all seriousness, though, I don't have anything against 7 but from my experience with it, it's just not for me. Too much extraneous crap like replacing the perfectly-functional "run" command with a "search" command because I guess someone at Microsoft saw Spotlight in OSX and thought "well golly, why don't
we have that?" instead of "great, another thing that I might ever use if I were the sort of person who couldn't for the life of them figure out how to come up with a coherent arrangement of items in a hierarchical filesystem."
About the only reason I'd consider moving to 7 is when driver support for XP inevitably reaches the point that XP won't work on whatever I get to replace my Eee - and by that point I'm hoping to have my switchover to Linux completed.
