I have a question about how apple chose to design the iPod interface portion of the iPhone one of the most distingushing features of the iPod was the click wheel. When all the iPhone rumors and fullscreen iPod rumors were floating around, everyone was saying there would be a virtual clickwheel. So, why isn't there one on the iPhone? Does anyone know if with the multi-touch technology the only type of interaction is can understand is straight lines? because so far that seems be be the only way to interact. single touches, and straight lines, can the technoloy understand circular motions?
