I'm on 11.04 as well. I'm still trying to find a good desktop alternative. So far there is not much and KDE certainly isn't an option. I'm keeping an eye on Mint as well but I'm not sure if that's going to be it..
Why are you still on 11.04? 12.04 is the LTS release and nearly everyone should be running that this point.
You're kinda unclear as to what the LTS stands for, aren't you?
If you didn't get it from my previous comment, the reason I;m still on 11.04 is because it's the last version of Ubuntu shipped with GNOME 2, i.e. the last decent desktop environment...
