After having one, it's really amazing and the form factor and random utility it brings (built in tripod, easy to aim flash light and be hands free). The screens just need work. The crease is a non-issue as far as using the phone, but the little screen protectors that manufacturers say not to take off will deteriorate after like 6 months.
I think it's close though and I do often miss my foldable.
Yes, but not all at once
