A couple years ago I finally got them to switch from their pre-paid flip phone to an iphone. That's also gone extremely well. They own a Thor RV which (no surprise) has a terrible OEM stereo. Replaced that with a carplay capable one with a giant (but pretty low res) screen and that's made their RV travel GPS integration far less buggy than when using plain old bluetooth.
TBH moving them to iOS from windows was far less of a painful process than I expected and I'm pretty apple positive. The fact that it just works and they really can't 'f it up makes a big difference. Now they can download all sorts of shit games and I really don't have to worry about the system getting hosed. If I considered how much I value my time and the frustration multiplier then it's an investment that has easily paid back in multiples.
