It seems no one here has actually tried using GNOME 3 for any period of time. I gave it a couple of days and switched over to XFCE. I found it incredibly annoying as a developer desktop (perhaps a minority user these days?). It's very hard to switch between applications, virtual desktops are basically broken, you can't have shortcuts for launching apps/programs, no focus-follows-mouse, and the GNOME developers don't give a damn.
A few days ago, I added experimental to my Debian apt list and apt-getted for about an hour until gnome-shell was working. Very unstable, partially configured, not really revolutionary, etc. Headed back to Gnome 2 only to find out that GTK 2 and GTK 3 have a hard time co-existing. Twas very difficult to get my system back to normal. I'm an idiot; don't be like me.
If developers are a minority of Linux users, surely it's still a large minority. Sadly, KDE3 was the last desktop I actually enjoyed using. KDE4 is still (still!) broken and useless and ugly.
You can change all that. Install GNOME tweak tool. If the setting is not there yet (not sure about shortcuts), either file a bug or look at dconf-editor until that time.
