Well, I don't own a car – no point because it's gridlock central here – my point was that people choose different ways to waste money, including cars in general and car accessories in particular. And some people expect to change cars nearly as often as they change phones.
I love some of the technology behind the Samsung Fold and similar devices but I don't think I need one and am not planning to buy one. But, particularly in Asia, where huge phones are, er, big, I can see demand for these being quite strong: a tablet that you can keep in a handbag.
