I thought Gnome 3.6 was a nice update from 3.0-3.4 (been testing F18). Solved quite a few of the nags I had.
I'm way more concerned about tmp on tmpfs though... that and now it's going to ship in 2013 :-/
Yea delayed again, anaconda, secure boot and fedup (fedora upgrade?) are what is holding the beta release up right now. I give them kudos for delaying and trying to ship something good, rather than something flawed at release.
