Fedora 15 has been released and has the full Gnome 3 experience, plus Gnome-shell extensions to make Gnome 3 more configurable. Luckily some of the Gnome developers are on the RedHat payroll, so, I'm sure that helped a bit. Without the extensions, I find Gnome 3 quite unwieldy. Poll in the Fedora Forums show about a 50-50 split as to those that like it and those that hate it. Guess we're back to the normal Gnome vs. KDE numbers again. And I'm back to using KDE. It was my first DE using Linux, and it feels like I'm home again.
I'm obviously a KDE guy. I didn't like the gnome 2.x branch but I found it usable. I gave a try last week to gnome 3.0: My God that was a terrible experience!!!
I dunno, to me Gnome seems to be transforming into a kind of "mac" for linux and I *hate* being told how to do things. Previews and demos looked kinda great but... wow, the user experience is definitely horrible in my humble opinion. You need way too many clicks for simple things and it's not keyboard friendly, at all.
I seriously encourage everybody to stay with the old gnome or any other DE.
