Well...not to be disagreeable, I've had the Flip 4 and now, since it came out, a Flip 5. Both are excellent products. IF you keep a semi-fresh screen protector film on them, the screen will not break/crack in the flex/fold area. I didn't try them for luxury, I tried them because they fit comfortably in my pants pocket.
I guess I could see it. I'm guessing you tend to wear pants with shallow pockets correct? It is a problem my wife runs into that woman's pants have next to no pockets. She ends up needing to store her phone elsewhere as a result.
Yes, on the shallow pockets. Also, I had the habit of putting my non-folding phone down when sitting, and then leaving it behind.(!) I would sit it down because it wouldn't fit into my pocket and I didn't always carry a hip pack. Except for the stupid high prices of the "fold" phones, they would put me right back in the non pocket fitting situation. (Although the extra screen space would be sweet!)
