I am a linux user, and I dearly love gnome.
Gnome 3.0 however or more particularly Gnome Shell is a turdfest in my humble opinion. The Gnome crew must be on drugs to consider this A Good Idea(tm)
Yes I tried the beta and am not just casting opinion willy nilly, and yes I know it will be adjusted, changed, tweaked and generally differ from the current snapshot. Maybe they will pull off some kind of miracle, but I can't really see it.. Gnome Shell is just a bad idea. I am not alone in that thought as many people have said much the same in various discussions such as on Ubuntu forums.
Oh well, XFCE is getting nicer ever release, its been one of my alternate desktops for a while, that and Openbox, plenty of other choices thankfully :]
Icon, because I wish Gnome devs would stop, rethink things and decide to build on the UI they have rather than start over with Gnome Shell.... /sigh
