A rather different observation from what I see. Whether the person is reading on a 6" ereader, a 12.9" tablet or a broadsheet sized newspaper, in my experience, they tend to hold it at close to the same distance where they find it comfortable to read. I have never seen someone holding a 6" ereader at 30 cm. a 12.9" tablet at 66cm and a broadsheet newspaper at 192 cm.

Since my eyes are are close to the same plane and I hold the ereader pretty much centred between my eyes, the difference in the distance between either eye and the surface of the device is pretty minuscule.

As for infinity? The prescription for my reading glasses was set so that with the ciliary muscles relaxed, my eyes are focused at 34.3 cm. You did bother to notice the brackets around the "for normal vision, that would be focused at infinity" with regards to the "my eyes are relaxed"? Are you having trouble reading your Google translations?

You do know that if, for example, you have your camera focused on infinity and you then place a +1.5 dioptre lenses in front of the camera lens, it would now be focused at .66 metres.

- I am not aware that a "broadsheet newspaper" is an "electronic device," and
- I would have to squint quite a bit not to see a dot twice in 34.3 cm and this is quite exhausting with the eye lenses set to infinity* and
- what has squinting got to do with attachment lenses on a camera?
- I have never seen anyone using a 13.3 inch EInk device at less than 60 cm reading distance.

Apart from that, 227 dpi is not designed for a reading distance of 30-36 cm, unless the reader values a pixelated image - 0.11 mm are not clearly visible from such distances only by an extremely poor sighted person.

I suspect that here the pixel size plays a decisive role for the use of the reading distance.

Aber jeder, wie er glaubt!

* Edit: afterwards, I thought of another possibility why it might not be important for you - the eye lens is set to infinity and reading at a distance of 34.3 cm; there are people who see only with one eye despite having two functioning eyes - such a handicapped person naturally does not need to squint when seeing nearby.

You can get by with this size and many do, but if you spend a lot of time marking up documents with a pen, you'll likely benefit from a larger screen closer to 13". The Elipsa, besides its weak hardware given the cost, is a 'tweener' size that doesn't appeal much.

I prefer to do this kind of work with 7.8 inches, rather than with my 13.3s - the distance is too large for me (~ 55cm), so that I don't have to admire the individual pixels.
Since the pixel size of the 10.3 is almost the same, the necessary distance would also be very similar (~ 50 cm).
7.8 has the same pixel count as 10.3 - there I see the same thing at the working distance of ~ 30cm, which is very comfortable for me.

With regard to inferior hardware equipment, I have to agree, of course.

One advantage that could be worth my hard-filched piasters: If the infinitesimal photos and illustrations that taunt you with tininess on a smaller e-screen were somehow legible and could even be enlarged on an Elipsa. I nearly stopped reading bios of Alice Bradley Sheldon and Jean Rhys to avoid the extra irks.
