Indeed, I think Samsung and Motorola took 2 different approaches when imagining their Foldables.Think Motorola is onto something with this. Phone with screen size of iPhone 11. But folds to half size. With little 2.7” screen on back with basic functionality that will often eliminate need to open it.
Don‘t think Samsung’s implementation, full size phone / mini tablet combo, that is still big when folded, is what the masses wants. They just want a phone. And many will appreciate 6.2” screen phone that folds to a much more portable size.
The price will come down if it sells. Also, they can crank out smaller and larger screen versions.
Samsung chose to go for the heavy user Phablet lovers, their typical Galaxy Note customer who still wants more. People who would even buy the 7inch tablets and use them as phones, very niche market in general.
On the other hand Motorola went with the mass appeal strategy, rather than focus on specs and screen size, they focused heavily on practicality and how this thing can fit in anyone's life.
