Ubuntu 7.10 is really great, amazing really. I almost never boot into Windows anymore, only for the kids to play a game now and then. If I get off my but and get more familiar with Wine, I won't even need to boot into XP for games.
-edit-
BTW this is leaps and bounds over say, SUSE 10. With SUSE 10 I wound myself having to getting my hands dirty in console, which I usually worked everything out, but with a large amount of cursing and such. Ubuntu 7.10 Gutsy, I've yet found compelled to bang away in a console window. Everything is automated.
