1000x800 approx. I was using it as shorthand for the typical reader 
resolution. The readers don't specify them in terms of *VGA.

The correct inversion would be:

NOT (I want to be able to draw figures that are legible possibly needing 
the user to wear reading glasses on a cellphone screen).

I.e., I don't want to assume the responsibility for legibility on such a 
limited device as a substitute for the user either using a bigger device 
or using reading glasses.

That's basically my conclusion as well.
