Im curious about the upscaled versions of touchscreens. Is there such device that is like a large computer monitor that is touchscreen. I guess kind of like what they use on CSI Miami [ Yes I know most of their computer screens are digital effects]. Or perhaps more like a screen used at MI6 headquarter in James Bond Quantom of Solace. One where you touch the screen to use the cursor instead of just a mouse. I guess I want a giant touchscreen that is compatible with my computer. Is there a such a product and where can I buy them?
