Here is something interesting. With touch screen features growing like crazy, Hitachi offers a new 65” plasma display with the Hitachi PXDUO-65P Interactive display, featuring 16 function buttons, 14 of which are customizable. It even has a three-button electric pen which should account for mouse functionality. Unfortunately this is one device that is not yet officially in the market but once information leaks out on these devices, you can bet it will be out in no time. Also, you can bet that the price for this display will not be peanuts compared to standard plasma displays today in the market.
