You know, I am a bit puzzled about one thing (among many others of course). For most part epaper seems to be the least power hungry choice (not that I am a tree hugger; I am of course, anyway, but in this connection less power means longer battery life etc.) but there is another option that, though it is not power-independent, should get by on very little. I know it exists, but much as epaper did for a couple of decades, it seems to be languishing, or at least limited to special purposes. What I am thinking of is some kinds of heads-up displays that can be worn like glasses, seeing the "screen" through some sort of lens system. I should think them to be perfect for reading etc, and afaik they are mainly LCD based, and accordingly power-conservative. They should be usable hands-off whether walking, driving, lying down, or in the dark. Potentially a 640X 480 or even 800X600 should be cheap. With a modest memory and processor modules they should be nearly everything the Kindles are, or more so.
Exactly, that makes one think further. They would be ideal for unobtrusive data representation in mission-critical situations... ahhh don't we know that language from somewhere? might THAT be the reason we don't see such devices: because they are *dual use?
on second thought, however, I rather believe we WILL see them, but only when we all have bought the clumsier things they have in that pipeline for years to come. and then we will wait a decade for integration of thought-controllability. image that: not even move your arm to turn a page: reader's coma. ralf
