I disagree, I think the Gnome 3 shell is a fantastic UI. The workflow is fast and quite intuitive as well. Besides, that is what spins are for. If you like cinnamon grab (or make) a cinnamon spin.
Further, I would submit that once you start actually learning and using the keyboard shortcuts in Gnome 3 you will also enjoy it. Just because it is different than what you are used to does not make it evil or bad.
I am not against this at all. I am probably stating the obvious, but Gnome-shell would still need to be just a yum install away and should not become a second-class UI like KDE used to be in Fedora. Personally I quite like Gnome shell, but I know far more people who don't. I also have an issue with its weight, but Cinnamon does not solve that either.
Most people I know swiched to fedora BECAUSE it was the only major distribution offering a full gnome 3 as default. Also if no one offer gnome 3 as a default desktop, yes no one is going to get used to it ... and UI is less likely to get improved. I personally like gnome 3 a lot and would swich back to debian if I yhad to change the UI anyways.
Also I belive than the people that flame gnome 3 the most are those doing everything in CLI anyways, windows® user find their way in gnome3 in 5min (not harder than Unity wich is on "the most user-friendly distribution for windows® users" )
Arthur, it's not about finding my way once. I have to use Windows for work and I want to configure Fedora to work in a similar way so I can utilize my motor memory to avoid even thinking about the UI. I could configure GNOME 2 that way, but I cannot do that with GNOME 3. I'm not a CLI-only person, far from it.
I used to be an IceWM user, but I switched to GNOME 2 because I wanted to use applets like NetworkManager. When Fedora switched to GNOME 3, I changed my desktop to LXDE. It's an acceptable solution, but it doesn't get enough love from the Fedora developers. For example, alacarte was totally broken in Fedora 17. That's the only way to edit the LXDE menu. Even though the fix existed, it was never made available to Fedora 17 users.
Fedora 18 has a new problem with keyboard layout switching. I cannot use Alt-Shift, GNOME wants me to use something like Alt-Shift-Space, and even that doesn't work reliably. I had to use some magic command to prevent gconf from messing with my settings. It demonstrates the attitude on GNOME developers. They enabled an incomplete feature that disabled the existing functionality.
I have no strong opinion about Cinnamon, but it would be nice to have a fallback desktop if LXDE stops working for me. And for that fallback to be polished, it would be nice to have it as the default. Not that I would stick with defaults when installing Fedora, it's more about priorities for the Fedora team.
