They're getting better every year though.
I have a Fold 4 provided by work and I'm in love with it. If I could afford it, it would be my main device.
The crease doesn't bother me at all, it's something you just ignore like the notch on iPhone.
Nothing broke yet and the reports of damaged screens are decreasing per upgrade they're doing.
So, yea a lot of people are beta testers for this with expensive devices and I suspect Apple is in the same situation, they're just waiting for the tech to improve before they go all in.
