The screen of jetBook seems really good and much better than I expected. I am wondering whether Ectaco is planning for a big screen device with the same LCD screen. If not, I would like to voice my opinion for them to think about it.
I would like to read PDF files made for letter/A4 paper and I believe many people would also like a device that does the job. I have been waiting for PlasticLogic reader but large screen reader with LCD screen used in jetBook may work better. I can see several advantages of making large-screen readers with jetBook LCD screen.
1) Durability
Since LCD has better durability than e-ink with glass substrate, LCD readers will have better durability than the same screen sized e-ink reader.
2) Established technology
Since the technology is already established, I guess it will be rather easy to produce screen with A4/Letter dimension and bring it to the market quickly, hopefully cheaper than e-ink equivalent.
3) Faster refresh rate
Since the screen update is much faster with LCD, users can skim through PDF files fast, which is not possible with e-ink screen.
4) Touch screen
Judging from many tablet PCs on the market, implementing scribble function with LCD screen may not be that hard.
Only weakness may be the battery life since LCD screen needs power to maintain the image. However, with replaceable battery, it may not be a big problem.
