German renowned institute "Stiftung Warentest" just tested two foldables (both Samsung I think) and had them 50.000 times folded and unfolded (they build machines to torture test stuff) and reported no creases.
50.000 times is over four years for 32 uses every day (twice every wake hour). Would be more than sufficient for a normal user think.
Crease distortion occurs immediately, day 1, first fold, and it's a substantial distortion.... but does not necessarily get exponentially worse like normal fatiguing plastic, but instead just gets worse slowly.
Yeah it'll last 50k folds but the crease distortion is definitely there in person.
I don't get the obsession over the crease, things that fold generally have creases. As long as it's not distorting things (which IME it doesn't and is hardly noticeable when in use anyways) it's fine
This is Apple; they value different things than most people… sometimes warranted, results in offering a much better experience, and pushes everything forward (see MagSafe -> Qi2 for recent example), other times they’re just regarded as late adopters. The detraction of visual aesthetics from folding crease is apparently one of such things that they care about.
