Well not new perspective but "The perspective", I've used gnome 2, kde, lxde, xfce, gnome 3 and unity; well gnome 2 was great but a bit old fashion when gnome 3 came out, sure gnome 3 (back then) was in his infancy, but now he came along way much better; I've never liked KDE (sorry) a truly beautiful DE but not for me, unity is a gimmick of gnome 3 and mac os x I just hate the global menu and overlay scroll garbage not to mention the launcher to the left and the HUD that seem to be designed in a train toilet in rush hour.
Gnome 3 is just perfect, very simple and sleek, then it is up to you as a user to make YOURS; gnome 3.6 you add Faience theme and icons, docky and some gnome-shell-extensions, then you will never look at unity or windows again.
I'll have to say a Big thank to Tiheum the Faience and Feanza creator he made Linux a beautiful enjoyable working desktop environment.
That's my point of view, but never-mind if it's Gnome or KDE or LXDE or XFCE or Unity or any other Linux desktop environment, just use whatever DE you feel comfortable with, because all of them are Truly awesome and gorgeous, and the best think IS they are all FREE.
