As for 11.04, I don't know if it's the promised break with Gnome as the default desktop, lack of ground breaking improvements, or what, but it just doesn't seem to be getting the clout 8.x, 9.x, and even 10.04 releases had. Personally, I'm done with non-LTS releases unless something EXTREMELY significant comes along. I guess you can tell that the switch to Unity doesn't impress me all that much. Honestly, I just haven't seen the same level of innovation I had grown accustomed to in past releases.
I could be wrong, so let's hear your thoughts.
