Why even bother with Unity?
I've been an Ubuntu user for 4 years now, but have never used Unity for more than the few days I need each new release, to verify that it is still awful.
The Mate desktop is what makes it usable for me. Use the Mate tweak tool to switch to the "Redmond" theme, and it looks pretty much the same as Mint Cinnamon, without the bells and whistles.
It's my distro of choice whenever I revive an old windows box for the newly converted. Especially on older hardware.
