I believe the keyboard on this is designed to be typed on like a normal keyboard, not with your thumbs, which addresses some of your concerns. I seem to recall hearing somewhere (possibly in an interview) that the 7 inch size was chosen because it was the smallest they could get with a keyboard that still feels nice to type on normally. As for the layout, the previous Reform has free keyboard firmware so you can change the keymap however you like. I assume this one will be the same.
