This is interesting....the Cinnamon desktop in Ubuntu is much more efficient than Unity. In Unity, when you are in a program and you need to access the program menus, you have to click the active window and then use the menu along the top menu bar. In Mint, they are where you expect them to be...in the active window.
I have to say, even though I have had Mint in a VM for a couple of months, I never really used it in work. Without a doubt, it is by far the most Windows-like Linux distribution out there, hands down. I think this is because the UI is so polished and aesthetically pleasing. The system fonts, the proportions, the transitions and visual design feels very "expensive" (like Windows and OS X). But some things I have to do regularly like connect to other Linux machines over a network or X-session are not the same in Nautilus. "Connect to server" has a different UI and is not as useful to me in an enterprise environment connected to a network with shared resources. But it works well once you get what has been changed.
