I like them. I think they have great potential and make sense in certain use cases. My preference would be the flip/clamshell style because it makes the phone smaller and with a large outer display you don’t have to open it as much.
For me the larger fold style is too big and heavy to use as phone. If it were a tablet that folded for travel or for easily storing in a drawer, that makes sense. Although I can understand if a traveling business man used a fold phone because in meetings and flights he they could use the bigger screen for work. But they probably also have a briefcase to carry it in.
Having said that, the current pricing is way, way too high. They would need to cost at least half or less for me to consider buying one. Around €350 for a flip and €700 for a fold seems about right to me.
I also think Motorola RAZR Ultra is the better folding phone at the moment as compared to the Flip 5, because the Samsung is very square and chunky, whereas the Moto is round and sleek.
