deborphan is so useful... I don't know why every deb based distro doesn’t ship it, along with synaptic (the Ubuntu Software center is some horrible piece of software).
I must admit to liking the idea behind Unity on tablets and netbooks and other tiny screens...but seriously who'd want to run that on a Radeon powered speed demon?!
+Dan Bowkley Unity isn't even good for tablets either... Gnome 3 is much better. I actually tried it myself... The Gnome Shell, workspace selector and the whole launcher are much better than their unity counterparts. Besides, the Adawita theme is perfect for touch-screen devices with it's big control buttons.
Haven't seen Adawita yet...hmmm....
