Umm, I provided a screenshot? I provided glyph sizes? I've done most of what I can think of atm.

(and the "lower DPI" directly contradicts the claim you made when you brought in the DPI argument,. which was that I can't view full page PDF on a lower-DPI device, i.e. the EEE)

You're not arguing, you're disputing. Bring facts to back up your assertions, and you'll be arguing.

The bigger question is whether I'm an anomaly (see the comments above on this page), and I can't answer that question. It's quite possible that others wouldn't be able to notice enough of a difference to warrant paying whatever the difference in price is (if, indeed, there is a "noticeable" (i.e. one that'll make the customer think again) difference).
