After reading through this Gnome 2.16 Preview, I have to say I'm a bit disappointed. Nothing in there made me excited to install this... it looks more like a bugfix release than any major feature release :( Course, this isn't the "official" preview that comes out a couple of weeks before a new GNOME is released, so we'll see, maybe it was just badly written (or maybe it is just that, not an exciting release).

Just found think KDE preview in the comments.... a very cool new K start menu is incoming sometime soon it appears. Still not a KDE fan, but that start menu is hawt!
