2 thumbs up for Linux Mint Debian Edition .. installed it end of May for our 82 year old computer hater and haven't heard one complaint, haven't had a single question about anything, no service call. Now I live the life of the Maytag repair man.
This user needs no specific software, just gets on the Internet via Firefox for email and to VPN into remote DB.
I read that Debian Linux powers the London stock exchange.
Many thanks to NLUG for helping me go from newbie to Linux user.
