With Gnome 3 I can launch, place, and switch all applications with a few keystrokes and without touching the mouse at all, all while "normal" people can still use the very same configuration. I like that it's basically just an unobstrusive shell to launch and switch applications.
People always complain that Linux desktops just mimic Windows 95, now that Gnome has done something entirely new (and good!), people complain that it's different to what they're used to.
