It is indeed faster and more accurate to use physical keys on a smaller device.

The competition is the exact same thing btw, with less screen and tactile feedback. Both will give you text thumb repetitive stress problems, but doing that on a hard screen will more so. Remember, this isn't theoretical, we used to use these all the time.

The drawbacks of a physical keyboard are in things like flexibility (you can't easily remap or change the size of the keys) and thickness.
