I set up Mint on an old Vista laptop for my Mum, who's 88 years old. She's a smart cookie but not at all experienced with computers. She gets along just fine with it and uses it for her Tesco online shopping and general web use.
She told me she'd had a phone call from "the Windows Technical Support Centre". What did you say to them, I asked, nervously. "Go away, I run Linux", she said.
