New technology for "touch" screen
I have just went to borders to see the new PRS-600. The unit they have there has an awful display. It looked very washed out. I was really disappointed as I really like the idea of making annotations to my books and papers (I am a university teacher, when I read a paper I make many annotations on them).
Then, I was visiting engadget and came across a very interesting video on a new technology to add a pen to "any" screen. Note that this thing does not add an extra layer to the screen. Wouldn't it be nice to see an ebook reader with this technology (or something similar)? That would probably mean a thicker region on the top of the screen (to house the sensor), but I can live with that if I get the touchscreen with good image quality Maybe Robert, from Astak, should take a look on this. He is well known for listening to forum members. Robert, are you listening? |

Or, put the touch layer UNDER the eInk layer. Manufacturers that do it that way don't sacrifice contrast like Sony does.

Plus you can't use Wacom touch screens (such as iRex use) with the finger - only the stylus works.

Aaand.. we're back to the OP's suggestion
I find it to be a great solution. |

Not really. Finger touch screens are not generally used the same way as stylus screens are. The only time the stylus screen impacts power usage is when you're continuously drawing on it. You don't really do that with a finger screen.
The power difference doesn't seem to have much to do with the layer being above or below the screen, or necessarily whether it's finger or stylus. The difference is most likely due to the continuous usage pattern of the touch layer. |

Actually they were talking about both. And most people seem to find pen only systems unintuative in comparison to touch screens.

But on my Clio (the vadem one) I used the stylus and finger continuously to make annotations. |

Other than that, it may come down to a tradeoff. Either a layer under the screen, a DUO type sensor, or a finger touch screen. The first two may not be as intuitive to use, but the latter will reduce your contrast. It would come down to what was more important to the user. |

Very much listening!!

Yes, I also have heard from reviewers that the new PRS-600 gives a rather washed-out look to the screen! Something HAS to be done. I will take your video and send it to my boss and the factory both!! I am intently listening!! |

As for turning pages, etc. I can use buttons (and maybe the pen for less common situations, like changing the book). Give me a good screen that allows pen based annotation and is sharp and I'll be happy. |

The problem may be the "spoiled by Apple" effect. Apple came with the iphone and its amazing touch interface. It is great and such and now people think that everything has to be "touch". But an ebook is not a general purpose PDA (where the touch screen is great). It is a device tailored for a single use: read. Hence the quality of the screen has to be awesome. This is the first priority to me. There can be no commitments here. After the screen problem is solved, as it is by good e-ink displays, you may start to think about adding annotations. And we do annotate using pens so there is no change on the way we already work. |
