My mother has just bought a Mac, on the recommendation of a friend who used to run a computer company. Urgh.
She's spent years on Windows, learning how to use it at the pace of a lobotomised snail - a pace that has been greatly slowed, mind you, by her prioritising of her desire to get her sons' attention with cringeing "Wahwahmycomputersbrokencanyoufixit" requests, rather than her desire to either a) use her computer or b) think for herself. Now she's got a different system and is going to start learning all over again. Dad - a formerly competent user (also formerly married to my mum), got a Mac on the same friend's recommendation and the pathetically needy requests for help with simple things have quadrupled since he did.
Friend: what were you thinking? Not everyone is a computing whizz, some people need to stick with what they know.
Parents: I'm not a Mac user, you now both are. That makes you the experts. If you think you're getting any help with your stupid new toys you don't know how to use, you can fuck right off.
