Unity's dash makes absolutely no sense to me. I voted for more customization, not on principle, but because I want to radically alter the dash every time I use unity.
On the other hand, I could have voted for not caring. Ultimately Gnome Shell makes a lot more sense to me and, as both desktops mature, I think Gnome shell looks more promising in terms of customization.
Of course, by 12.04, I might shove them both if XFCE 4.10 looks good. XFCE 4.8 is already well on its way toward excellence.
In the meantime, I've basically given up on unity.
