This is an open ended question for anyone with the knowledge to answer... 1)What are the limiting factors preventing a Liquivision X1 type of display from being used in hockey puck $400 type of computers? I assume cost, battery considerations, and perhaps size of the enclosure but I don't know for sure. Also what is the chance of the component cost coming down dramatically? 2.What are the memory requirements/limitations for entry level hockey pock computers? How feasible would it be to have display user controllable much like you can control your "desktop" with Windows. 3.How hard/what cost considerations would there be for entry level computers to have software choices so that you aren't stuck with Buhlmann derived algorithms or having to ignore your computer on occasion because what it's recommending is not what you feel to be best? Just in general, need all of these features only be in very expensive computers? Is there anything inherent (other than the display question) in these changes that have to involve great cost? With respect to the display question if cost is the main issue I'm wondering what the volume differences are between for instance Liquivision and Oceanic. You would think Oceanic would have some volume advantages (but probably not enough at present to be used in low cost models).
