I just wanted to throw this out there:
Gnome 3 sucks! Whoever designed this can't possibly do any real work under it. I think we've reached the point where the Gnome desktop has been made user friendly to the point of being unusable.
The "Gnome Shell" interface is a HUGE step backward for productivity. Oh, it looks pretty and all, but 3 clicks to get to an application? Oh wait, I can open them "faster" if I start "TYPING" the app name! If I have to sit here and type to open stuff, why not just open a terminal where I at least have tab completion - and why did I buy a mouse? Let me be fair though, I can add (huge) launchers to a "favorite apps" dock that I can then launch with a just 2 clicks (1 click to get into that aspect of the shell and another to launch).
Then there's window management: No minimize buttons, no 1-click to navigate list of open windows. They claim this is great - that now when you're working in an application, it's just you and that application. That's great, but when I'm working, it's usually just me and 20-odd applications.
I even tried the fallback method, which is supposed to be like Gnome 2 in operation, but go ahead and add launchers to the panel and every time you click one, Gnome will crash. Couple that with no right-click function on the panel and... what? really? no right click? How am I supposed to move launchers to where I want? How am I supposed to remove them after I realize that clicking them crashed Gnome? Manually edit the menu xml files????
I've been using Gnome 2 since there's been one, so perhaps I'm just set in my ways, but my intent is to not use anything that requires me to use Gnome 3 if I want to use Gnome, including Fedora 15 (which, I've been using Fedora since there's been one too).
Perhaps when I have more time, I'll look at forking Gnome 2.
