Wow! Did not take long for the abused and angry Gnome Zealot Defenders / Apologizers to jump right in and start whining! I have tried every major version of Gnome 3 and I just do not "get it" for desktop operation. Now interface wise for a tablet I can see it being ok. Thing is, it may be a little heavy for tablets. KDE is trying hard to "get it's mojo" back, but that too is an uphill battle. XFCE is a genuinely good alternative mid-road solution for a lot of use cases.
I really wish the Gnome haters and the Gnome Whiners would give it a break already! If you like Gnome3 GREAT !!!!!!! USE IT!!!!! .... If you do not care for it, Use Something Else! Personally I do not really care for Gnome3 all that much. Do not really care for Unity either (desktop usage!). XFCE 4.10 has made some solid progress and these days works reasonably well for general desktop usage. There are those of us who still care for *GENERAL* DESKTOP* USAGE* !!!! .... you know...mouse ... keyboard.... monitor...tower ...and 2 browsers open, OOO open for writer and Calc, a terminal open, Xchat open, and some solitaire open just for grins....
All this Gnome3 hatred from both sides... can't we all just get along?
Last time I tried XFCE, it offered the worst customization of any DE I've tried, however, that was maybe 3 years ago, so I'm sure it has significantly improved since. I am interested in trying XFCE again, although I don't see it likely replacing my LXDE and KDE setups.
Xfce has really improved in that time. However, to be fair, so has LXDE.
