      I believe that the poster meant to say, "Seven years after I noticed it..."

      Electronic Paper [wikipedia.org] was invented at Xerox in the 1970's. It's a LOT older than seven years. The only reason why people are noticing it is that advances in electronics are slowly making it practical.

        • What do you mean by "monochrome"?

          Monochrome. As in, the display only shows one color. (Usually orange.) You may remember back when the stock exchanges used the large orage display boards rather than their nifty, giant color screens?

          Do individual plasma cells support multiple hues?

          Plasma displays can be built to provide differing levels of Red, Green, and Blue. However, the simplest form of the technology is to have each plasma cell either on or off.

          No, Fairly old CRTs and LCDs only had one cell per pixel, for grayscale. Really old LCDs had seven segments per digit. Really old CRTs were character oriented, and you had no control over individual pixels (back when ASCII art was the height of computer graphics.) Ancient CRTs were vector oriented storage scopes, allowing you to draw lines, but not erase them without erasing the entire display.

          You kids these days and your fancy bitmapped screens.

    I wonder about the software in the device. From the article I understand that content "can be delivered and bought through TIMs mobile network via a regular SIM Card within the device". This may screw up the device, not only because the provider can ask for insane amount of money for the service, but because it may not have what I want to read.

    Everyone seems to be complaining about the company involved, but I see this as a revolutionary development. The problem I've always had with tiny devices is tiny screens. It's great to have the ability to surf the web on your phone, but why bother when you got a 1"x1" little screen and have to squint the whole time. Watching movies on a 1.5"LCD just isn't really that attractive. With something like this applied more in the industry you could fold out your display when you are sitting about, fold it up when you need to move and never miss a step. Could be a great development for lots of mobile uses. Even if this model and company don't pan out, as long as the product makes it to market and wows a couple of people, it could indicate a trend that could expand into further possibilities, which is always a good thing.
