The one thing I hate most in this world is saying I was wrong. I always think of Fonzie on the show "Happy Days" as he struggles to admit his only mistake in that one episode. Well I stand before you hat in hand as I just loaded Gnome3 on my laptop. I spoke ahead of myself in my previous post stating that Gnome3 looked too busy, I think I said "hot mess". I was so wrong...
This wasn't an easy install on Ubuntu 11.04 I had tons of issues from no desktop at all to it even cracked my KDE installation. I ended up booting into recovery mode and I found an amazing post on the Ubuntu forums by user slooksterpsv.
[HOWTO] Fix common Gnome 3 install issues in 11.04 - http://ubuntuforums.org/showthread.php?t=1742343
My impression of Gnome 3 couldn't be more positive. It is beautiful, it is production friendly, and it is clean as whistle.
I complained before that it crowded the desktop, not at all. Your desktop when idle is completely blank, the way I like it. When you have a million things going on you hit the 'Activities' menu item and it arranges your open windows for you to jump to what you need to go to, it also allows you to jump to other workspaces (desktops). I believe this enhances the abilities of having those additional workspaces to you disposal.
I'll do a more formal review soon to show it off. I don't think what I've seen out there right now does Gnome3 enough justice. So if you are horribly frustrated with Unity, and KDE leaves you a little bored, then definitely follow the link above and go with the Gnome3.
