Snow Leopard works so great! I just put the disc in, installed quickly, and it works great! The people saying they're having problems are few and far in-between! If you've been holding out, why wait? Just go for it! . . . (Forgive me for trying to rant positively, I'm just sick of reading the threads about people who are scared to upgrade because of the newbie posts that are reporting problems.) Tried something POSITIVE for a change!
