Tried to use Unity with 11.04 for a few days and couldn't handle it.
I use Ubuntu on my work PC with two 24inch monitors and just trying to get work done juggling between these two was a nightmare.
I don't want to be searching for file names or program names as the main way of opening things that I don't want to make a shortcut to.
I use the desktop regularly to place things in and for easy access. Why deny me this space that my monitors provide to lock me into a laptop friendly interface?
I've since changed to Debian Squeeze and am loving it.
A shame really as Ubuntu was the distie that got me off Windows forever and down the path of linux enlightenment.
Thanks for showing me the way Canonical, but the path ahead has no room for you now...
