I respect your opinion, but for me is it hardly a gimmick. I don’t need a tablet in my bag to view websites that aren’t compatible with mobile layouts, I have a tablet in my pocket whenever I want. Sure it’s not for everyone, just like iPhones vs Android, but the form factor of foldables absolutely solves the needs of some customers and I’m grateful there’s a line of products out there that fits my needs.
It took me a week or so to get used to the form factor but since then I can’t imagine going back to a slab. Different strokes for different folks.
