That's because you are thinking about it only as a phone. I got Fold4 in attempt to replace my laptop which I have to carry around almost 24/7 due to work. Fold4 has been successful in doing so 95%. It's still no replacement for laptop, but paired with comfortable bluetooth keyboard it's more than adequate for a quick fix or slight bit of work.

This is the second year I've had it and I am yet to run into problems. I do have original Samsung's case for it because that was the only way to get a pen for the phone. I played with new Fold6 and I can tell you it's far more robust and better made, so I'd expect even fewer issues with it. Fold4 without case is a bit slipper and entirely too heavy. Something new version addresses very well.
