I use GNOME every day. What I like is that it isn't to much. The main use to me of any window manager is to use my mouse as little as possible, be able to tweak all of the underlying hardware and peripherals and get access to my tools with as little interaction as possible. And I want it to "just work" whether it is my home desktop with 4 monitors, or my 14" desktop. GNOME delivers just that for me. Nothing more and nothing less. Of course this is just my humble opinion.
