Re: I feel someone should say.
Personally I like Unity too, for casual tasks, it's presentable, and more keyboard friendly than gnome or KDE.
For other work, other desktops work better, or better still something minimalistic like Openbox or I3, especially if I want to squeeze as much out for a bit of gaming.
When I'm using more than one monitor, I3,Xmonad or another tiling window manager is my preference, re-parenting/compositing window managers just don't do justice to the advantages of an extra screen or two.
