I've got to admit I'm impressed by GNOME. As happy as I was with my old windowmanager setup (Window Maker), there's a lot of coolness here. Didn't really expect to be using this for more than a couple of hours to play with, and I think I may be hooked.
Maybe I'm just happy that my OS can do the whole desktop thing. Little icons, cute pictures, file managers and overly configurable dock/taskbar/menu thingies... And it doesn't suck.
