Although both the 505 and 700 screens may be anti-glare to different degrees, I believe it is the distance from the e-ink screen to the touch screen on the 700 that makes the difference in the clarity. Sony may have believed this design necessary to incorporate the LED front light.

Huh? Virtually all PDAs use resistive touchscreens. Not sure what finger gestures have to do with this. The 700 absolutely uses a resistive screen. The problem with resistive screens is that even the highest quality panels lack excellent transparency. This is much less of an issue for use in products with a backlit LCD display (PDAs, smartphones, etc.), but becomes very obvious on an e ink screen, as the 700 demonstrates. Resistive touch screens seem inherently unsuited for e ink. I suppose they were used because they are cheaper and more available than other types. All in all, just a shoddy piece of engineering on Sony's part.
I'd say the touch screen is responsible for the poor contrast and glare. You're probably right about the clarity. The slightly fuzzy appearance of text would likely disappear if the touch panel sat nearer to the e ink screen.
