Would be annoying in your pocket. Would be annoying in 2 hands. Would be annoying when you put it down and try to use it on a flat surface.
It would potentially be better for phone calls. But the speakers already seem to work just fine without the curve, they dont need to be next to your face anymore. Phone calls are one of the least important features of a phone these days tho. Or i should really say least important feature of a pocket computer.
I totally agree with you. The phone almost stays in our pant pockets most of the time and a vertical curve is useless there. If it sits comfortably on the cheeks, then it would pick up oil from the face. Just a no go for me and many others with oily face!
