You make a great point, no software in the history of ever has had any ability to change the size of the font or to scale the display size. I completely forgot that humans need to hold their heads perfectly still at a perfectly measured distance from their screen in order to function.
If you need giant font and to move around a lot, then what's the point? Do you really want to more a round a ton while trying to type? I still think this is worse than a monitor in almost every way.
