Distance is entirely dependent on the device.
When you're studying in school, books are about 30cm away from your eyes when on the school benches.
When the device is small, and the letters are small, there's no other option than to read close by. As long as you don't stare multiple hours to the same distance, but regularly shift between distances, the eyes will never grow accustomed to the closer/further than optimal distance, and no damage is done.
Occasionally to get the eyes fixed on a 30cm distance, 40CM for the Jetbook is indeed the optimal distance.
Just as long as you have multiple book sizes or devices or monitors, say a 5" e-ink reader, a Jetbook Color, a 24" monitor, and you read evenly on those (holding the jetbook closer to you than the monitor, while further away than the 5" e-reader or a book),your eye will adapt and not become stagnant.
It may be difficult in the beginning, especially if you already are wearing glasses, but it's important to LEARN to read from distances that are just a tad outside of your comfort zone!
Many people could RE-TRAIN their eyes, and some might even entirely get rid of their glasses!
I've applied these principles, and they have helped me avoid glasses; and I DO read a lot!
