I tried both of these interfaces when that I upgraded to Ubuntu 11.04 Beta 2. Unity did not stay installed very long. This interface has matured to a stable state however the interface did not appeal to me. Unity is plagued with overly large icons and lots of blandly bright colors. It’s like the screen was designed by Crayola and not Canonical.
After following some steps I found on Ubuntu Geek, I added the PPA for GNOME 3 to my sources.list file. These steps, I’ll include in a separate post.
