Two caveats are important in looking at these product generations. First, no one can really predict what products will penetrate the market; for example will the trend be to one big multifunctional screen that connects with everything or will there be a stronger trend to lightweight portable “personal displays”? (One should recall that several years ago many people thought the idea of a camera in a mobile phone was preposterous.) Thus whether these will be the specific products in the future is hard to predict, however be believe that these products show the kind of technology development (to color, high resolution, low cost etc.) that will be necessary in the coming years.
Second, display media can change over time.
