Unity in 11.04 is a different beast than the thing in 10.10 netbook. Unity11.04 is rewritten as a Compiz plugin for performance reasons. Unity10.10 was based on Mutter/Clutter and suffered poor performance b/c of that (among other reasons).
Anyone who used Unity in 10.10 should give 11.04 a new and fair shot since they are 100% different things.

The only issue with that is if you don't have a spiffy OpenGL video card. Mutter and Clutter have come a very long way since the decision not to use them.
