It's funny that at some point we'll have completely different tech and all those screens would look like old tech :)

Anyway, I have fiddled with it few times in stores.

* It feels nice form factor for holding. but the folded 'passport' screen still feels it's not yet caught by websites or apps.

* The claims are Apple is suspected of doing this form-factor (and as a display manufacturer I guess Samsung could sniff it...), meaning Samsung tried to be first. like the Galaxy Edge.

I guess the discussion over the form factor would be more valuable in a year or so after Apple drops their product. If enough actors has similar form factor, I'd expect designers to caught up with it.
