I have not yet seen an eink display, but I like all that I am hearing about it, except its size.

That's right I don't mind that it is black & white, even a bit slow in page turning, I need to read stable text, a book I can put down and pick up where I left off without re-booting. I can live with limited interactivity, and wait for all other improvements - but not size.

A4, unless you can fold it is just too big, thumping around with a clipboard size device does not work for me at all. Don't get me wrong if I could fold it up, A4, even A3, would suit me fine.

But until then, it just seems so obvious - A5 (14.8cm x 210cm). Scales up to A4 printing well, scales down from most A4 well enough to read with ease (given good resolution). It can be printed on A4 either scaled up or simply in booklet form.

A5 with extra border and control space can be shoved into most bags, of even hung off a belt with out much problem. A4 can be to if you carry a briefcase or don't mind looking like a 19th Century courier with a large dispatch case banging about.

I am a hopelessly untidy individual, when reading, without some handy bag or big pockets, I slip my current reading into my shirt (hating to hold anything in my hands). A4 is too big A5 about right (especially if it is thin).

So my message is - get the size right, there is little practical choice but A5 eink page. Then start improving the rest.
