I have been using Mint since Mint 6 came out. Mint 8 is very nice but only a Firefox 3.5 issue which is not caused by Mint. See the thread below.
Right now using Mint 7 until I can solve the Firefox issue.
Happening with two different PC installs.
I am only at the user level for the past six years. I want to run Applications, not Operating Systems. Mint has been very good for that.
