I'd been looking for a tablet (or something) that displays the same size as an A4 page (or letter for you US guys).

I didn't quite succeed but close with a Asus C302 chromebook.  It has 16:9 ratio 12.5" screen, awesome battery life.  I have quite a few scores that just drift on to two pages so cropping them tight and using the vertical scrolling function allows me to see the full score.

I also purchased a bluetooth pedal however it forces the chromebook into landscape mode.  I have to manually override the orientation with the chromebook settings (CTRL+SHIFT+rotate) but this is annoying.  I did read another post on this, any news on a fix?

Anyway, highly recommend the chromebook.
