For anyone who has tried the GNOME 3 preview (from GNOME.org or the Fedora 15 alpha) what do you think compared to gnome-shell on 2.x?

I used Fedora for a week to see what life would be like...

I realize now, that gnome-shell (if/when it is un-broken) should be available on GNOME 2 though, so we might be able to have our cake and eat it too . . .

Does anyone have either working on 11.4 atm btw? I installed gnome-shell but when I go to activities and mouse over a window it disappears, flickering, general brokenness. Hints?

(new here, so can't post a poll!)
