I tried Cinnamon on my netbook for the best part of a year. Unfortunately I was using Linux Mint which didn't seem to allow you to log into Unity, and any questions about this on their forum were answered with "Why would you want to?"
In the end I grew tired of the same user interface we all used from 1995 onwards and I felt Cinnamon wasn't as intelligently designed as Unity. Lack of file search really killed it for me. I had to switch back to Ubuntu.
