Not what I hoped...
I converted from Ubuntu 11.10 to Mint 12 yesterday morning. From the start, I was disappointed...Mint didn't recognize my monitor setup and limited me to three resolutions, and 1280x1024 was the best/closest I could get to optimum for my widescreen monitor. It also wouldn't/couldn't refresh package information and seemed to take forever downloading and installing updates. It installs with a plain black desktop background, which made me think at first that something hadn't installed correctly until I figured out that no, that's just what the dev team thought would be the best first impression. Guess what, folks...if you want to bring new users (especially non-developer types like me) into the Linux fold, first impressions do matter. When I installed Ubuntu 11.10 a month ago, I didn't have to tweak anything other than installing Chromium and removing most of the icons from the Unity bar.
Suffice it to say I've reinstalled Ubuntu 11.10.
