I'm really glad you brought this topic up buddy215. I've been using the Classic Ubuntu for a few weeks now on 11.04, and love it!
I have only encountered one problem ( such as a friend of mine did ), but it's easily fixed. The problem was that there were no title bars on any windows I opened - to close them ( such as Firefox and Thunderbird ), I had to go to the bottom panel, click on them, and close them from there. So.... if anyone encounters this, go System/Preferences/ select Compizconfig Settings Manager, and under effects put a checkmark in the box next to Window Decoration. This will correct that problem.
If perchance anyone shouldn't have the Manager under preferences, they can install it from Synaptic Package Manager. As you can tell, I prefer the GUI method over commandline whenever possible - hee hee.
One other thing I did notice - normally when I want to set up the Compiz effects ( on a Debian-based system ), I first had to go to System/preferences/Appearance, and select the Visual Effects tab, tic Extra, then let it install the packages it needed, restart, then go to CCSM and have fun. In 11.04 ( Ubuntu Classic ) that tab is no longer there - I'm guessing that it's already installed because of Unity?
If I should happen across anything else out of the norm, I'll post it on this thread.
