I am in an odd in-between position.
I have no issues with the size of the keyboard. (I use std qwertZ, not the shifted qwertY)
But on one hand the screen is too big to use one handed as touch only, while keeping a secure grip. My thumb is incapable of covering the full display.
On the other hand I'm so old that a smaller screen, in a font size I can read effortsless, would leave even less data on screen....
