I want color, but most things i like color for, also do better with a much larger display.
If they could make a 17 inch tablet, and keep it at say 1 1/2 pounds I would be happy. Lighter than that and I would be ecstatic. |

Note, the 260/250 ms is a little misleading. That is the raw response time, but because of ghosting you almost never see that type of refresh done (unless it's a partial screen refresh). Most of the time the device does a "multi refresh" consisting of several stages every time you turn the page. It either inverts the current image, goes to a black screen, etc, and then refreshes the next page. There are typically 2-3 iterations of the response time that make up a single page turn (depending on the device's implementation). Typical real world page turns with existing eInk are more on the order of 750ms. So if the color has a 10ms shorter response time, you'll probably triple that for a single page turn. That would put it more on the order of 720ms vs 750ms for a page turn. Assuming everything else is the same (multi stage refreshes, processing time, etc), which may not be true. |

Would color be more difficult on the eyes? Curious!

No, that's a legit question. I work on commerical phone systems all day, and I've seen some displays, where the color was washed out, and so, it was more difficult to read things. Muddy pictures are not good pictures.

17" like the size of a computer monitor? The battery would be HUGE to power such a large screen so the weight would be about that of a laptop. Until battery technology improves we won't see portable 17" tablets of any decent battery life with low weight.
I think a 10" screen would be fine for most books. They have to worry about contrast as well, it seems to always be a compromise between contrast/pixels per inch/brightness/screen size. |

Why BLACK flash instead of WHITE flash
What I've never understood is this: the eInk works by having a Sagan ("billyuns and billyuns") of tiny particles, coated white on one side and black on the other. Apply charge, flip them all one way, selectively apply charge to flip SOME of them back the other way.
So... why do they have to flash BLACK and then turn some white. Why can't they flash WHITE, and then turn some of them black. That would certainly make for a far more esthetically pleasing experience. I'm sure there's a reason, but still, curiosity and the cat... |

Taiwan LCD panel makers have brought the original US epaper producers. They are focusing on this type of technology as the traditional LCD monitor profit margins dries up and their TV panel technology is a generation behind the Japanese, so the profit there is not looking too bright until they upgrade their production lines.
But they got the resources to make epaper big and the devices are still very expensive (compare 20 inch LCD panels with cost of E-inks... vs the retail price) Colour epapers may appear in 2010, but won't get anywhere until 2011. Who needs colour epaper when current generation devices can't even display large size,, picture filled pdf properly! E-readers in 2010 must have 9 inch + screens and 1024 + resolutions, approx 200g in weight, good battery plus good software. All the respond time and stuff has little impact unlike normal LCDs. customer really want is bigger screen, easier to use, better page display layout... n Off course: CHEAPER! |

I have to disagree on one point - I don't want a bigger screen for my ebook. If I wanted a 17" screen I'd be using a tablet PC. I want my ebook to be easily portable to take with me everywhere. I don't want anything larger than the Sony 500 I've got right now (or the Rocket Ebook I had before that).
