I installed SP2, or rather I should say my computer installed it, and other than resetting my default printer to my fax utility, when using IE (I just had to reset it, of course), I've had no real problems with it at all.
Strangely, it seems to have sped up my web surfing some. I'd noticed lately that most web pages were slower to load than I was used to. I checked my broadband cable ISP speed, and everything was normal, but pages just were slow to load. After SP2, I'm back to fairly fast loading again. YMMV.
