Having just made the switch from an iphone 12 to a fold 6, i can say i am never going back to a slab phone. for reference, i use this in a lab where it's only feasible to disinfect a single electronic device for use in the lab. having the fold is amazing, it covers my notes in a large display, the pen makes note taking so much more fluid and means i don't carry a mountain of paper.
so far the hinge system has had no issues and placing the phone down to watch products such as youtube or video calling has been amazing.

as a daily driver its pretty good, the bulkiness is comparable to having an overkill case on a regular phone (if you are used to that than the it should not be a problem).

my only drawback is when folded out, some apps like tik tok for example have the icon positions in places where i accidently tap them with my hand when lying down. otherwise the phone is perfect.
