What about KDE? Personally I've always preferred it to Gnome.
Pal replies: yes, there are other desktop GUIs... as mentioned, Mint with Cinnamon is great. I also use CrunchBang with its appealing minimalist OpenBox GUI on another machine. And yes, you can (with a bit of effort) replace Unity or tweak it to avoid some of the worst faux pas. However, my point is since Unity is the default/standard GUI for Ubuntu and likely used by the vast majority of Ubuntu users, who themselves represent the majority of Linux users, it behooves Ubuntu to avoid these needless mistakes... it should work well for most users most of the time, without them having to resort to other tactics.
