I'm glad I found this posting; if I could further the conversation a little...
I am currently triple-boot (well, quad- technically, since I stille have 11.04 clogging some drive space) Vista, Ubuntu 12.04, and Mint 14 Cinnamon; all 64-bit.
I didn't like what I've heard about 12.10, so I thought I would try Mint, which I do like-- Cinnamon is a nice DE, but I also actually like the Unity dock-- it gives me quick-launch buttons, which also tell me what programs are currently running, even in other desktops, and I can jump to those desktops quickly by hitting that button.
I also like desktop cube, but I guess I am out of luck, there. :/
So, is there a Unity-like dock that is better suited for Cinnamon?
