As much fun as giant touch screens look (no thanks to minority report) they're not very usable for hours of work. Try it out for yourself, sit at your desk raise one or both hands towards your monitor as if it was a touch screen and see how long you can hold them there. If your hands are above your heart they'll get tired pretty quickly and eventually feel a bit numb.
