KRAD, hang on to those ideas, the great thing about the future is that it's always moving forward! (barring the occasional interference by religion, politics, and capitalism anyway)
My point is, the market may not be quite ready for the format yet, but it's only a matter of time, and I doubt it will be very long at all. Soon enough we'll have self-lit flexible screen OLED readers in full color and highly efficient, needing very little energy to run and charging quickly. They'll be slim, portable, and (after not too long) affordable. The readers will be embraced, first by doctors and nurses, government officials, then by students and commuters alike for their ease and versatility, and soon enough by everyone. They won't phase books out, those are too entwined with our cultural identity, but it will throw the printing industry for a bit of a loop and hopefully save at least a few trees in the process. Soon enough we'll be laughing about how clunky and awkward those PADDs on Star Trek looked in the 80's and 90's. E-books will rise again.
