Play along - create a PinePhone keyboard

[BronzeBeard]

the hinges are on the side so unless you have got a head thats flat and round i dont see it as a problem. youre not going to try holding it in landscape for phone calls

Grip would be my bigger concern. Are you supposed to wedge your thumb between the gap between the phone and keyboard? Hence my comments about how far the hinges allow the screen to flip. If you can do a full 180 degrees, then it's no big deal. Otherwise, the keyboard is going to need a mic and a speaker on the backside if you plan on reasonably holding the device to your ear.
