Actually, all you'd probably need is a different screen and pen driver.
The problem would be performance--it's much slower to scroll 1-bit screens
"against the grain" of their memory layout than with it. This is probably
why the OmniGo uses a hardware flipping method.

Also, most of the Zoomer software is hardcoded for the current screen size,
so you'd have to flip and reboot between using landscape and portrait mode.
