I will add as someone who just got the z flip 6 as my first foldable, the biggest thing I'm enjoying and that the people around me are noticing, is that I don't get "drug" into excess screen time just from looking at a notification. I'm more likely to dismiss it or deal with it quickly from the cover screen, or make a more conscious decision to open the phone up to engage, if that makes any sense.

I don't think it's recency bias or just trying to justify the purchase, and it's probably fair to call it a really expensive solution to a self control problem, but it has changed the way I use my phone in a more significant manner. I also enjoy the form factor in the pocket, and for the security for NFC payment/taps, but that stuffs been covered plenty of places.
