I used to have to clear out malware remotely from one of my grandmother's computers about twice a year, for several years.. I was so happy when it finally died, bought her a chromebook, which she was very happy with.

Chromebooks are probably the single best option for a computer with a keyboard. I wish the chrometops were a bit more compelling, as I'd probably switch my other grandmother (ubuntu 16.04) over. She has one program she plays a lot (since 1996) which runs under WINE.
