From the end-user POV in my respect, I remove all instances of mono. I'm running Cinnamint on my main machine and it just runs a lot more reliably afterwards, with less crashing. No banshee for me. Mint could still use some polishing but that's understandable considering their migration off older techs. Cinnamon definately smacks your desktop performance (Athlon X4 955 and Ti550 with Xedgers binary) compared to the likes of Mate, but eh. It's rool purdy.
