The people in this thread need to step back and evaluate their priorities. It's a *window manager*. It allows you to move windows around so that you can do what you're supposed to do with a computer, which is *use applications*.
From experience, Gnome 3 does an extremely effective job of allowing you to manage windows, while getting out of you way so you can actually get things done. What's more, it has an easy-to-use interface for opening applications and configuring system settings, and it's visually elegant.
Gnome 3 is intended to be better than Gnome 2, and it is; you just have to give it a chance. Stop being so self-righteously petty.
