I was reluctant to try MINT at first as I have had some bad experiences with KDE and other desktops and Linux Distros. Yup ! MINT *is* Ubuntu done in a more succint way. I am the kind of PC err that likes to push OSes to the MAX. As of late I like experimenting with Linix distros on PenDrives. Ubuntu Lucid Lynx works really well in this area - but MINT works better! I tried installing Maveric and Natty on PenDrives but they are prone to getting their pipes busted and have performance issues. If I (personally) cannot get an Ubuntu Distro to work effectively on a pen_drive then I have to basically scrap it because it is an indicator that in may degrade in performance over time.
I am not taking anything away from Ubuntu or Fedora .. they are both exemplifications of what fine and economic programming can do in an operating system and it is obvious that MINT had borrowed a lot of the assistive techs from Maveric - ie; the zoomy windows with mouse shuffle- but MINT has a very distinctive type desktop that perhaps can be more or less referred to as a theme concept.
However .. since after updating (as I had done likewise with Maveric and Natty on my pendrive) I had a seamless and non-broken system (where the same results did not emulate over the later two distros of Ubuntu.
It may be that Natty will eventually flatten their problems with 'Unity' but in my own opinion , they will have to do a stop check and go back downstream, grab some of those more reliable tools, and filter out the floatsam and jestsam upstream which seems to be affecting Natty and Maveric on the pendrive installs.
Util then .. I'm gonna have some fun exploring MINT!!
