Another highly satisfied Mint user here...
... such a refreshing change from the fiasco Windows has become.
And before the Microsoft Online Reputation Managers come in I want to point out that:
1. Mint has worked with ALL my hardware with NO recourse to file editing or the CLI.
2. I have been able to find open source software to replace ALL the Windows programs I used.
3. The user interface is so similar to 2000/XP that there has been no 'retraining' required in my business.
tl;dr? Here's an executive summary: 'Easier, better, cheaper'
