...honestly, its kind of annoying having to manipulate my hands as much as I do to scroll and type, and pinch zoom would just make it worse. I am used to using a stylus, where, ultimately I had to move my hand very little.
Everyone is so hyped over touchscreen technology. Just wait until you have to walk up to your 75" flat panel and swing your arms around to get it to scroll through the guide. How is that easier than pushing a button on a remote?
Sometimes newer technology isn't better. Can you see CAD operators moving their arms around in their cubicles to move their 3D rendered designs, rather than dragging a slider with mouse?
Sorry for the tangent, but I agree, Pinch-Zoom is not necessary, at all.
