I have a relative in her late-70s who isn't anti-tech, but she is wary of it. She doesn't like touch screen devices because they "do things on their own" (actually, when she points at something she inadvertently touches the screen and something moves that rattles her).
She's forever hunting around for old Blackberry devices because she likes the "physical keyboard" if she needs to send a text message.
And she has a cheap "flip" phone just for making phone calls because she doesn't like holding anything big and heavy to her ear (she's not had huge success with bluetooth ear pieces), and she knows it won't start costing her mobile data.
You couldn't tempt her with an Apple or Android device if it was £50.
