Argh don't bother! Been using a 11.10 beta for a couple of weeks... Decided to wait for release and give it a decent chance, and was just as terrible.
I hate that you no long have the option for "gnome classic" - only Unity or Unity 2D.
In my option, Unity is a failure. I am not particularly scared of big changes in new desktops, but Unity does not feel intuitive, and the window manager "feels" buggy and cluttered. Will try whole new distros this week (hopefully Mint, JoliOS, and Fedora), but if I were to stick with any of the heavier distros I know so far, I'd stick with 11.04 + Gnome 2. My work computer has been on a deeply customized Arch Linux, and it's the best THING EVER lol
