Apple, perhaps the industry’s leading innovator, chose to do the simplest thing possible, according to these patents. While space on the front of a product may be all but gone, recent patents show that Apple is prepping a touch screen interface on the back of one of their devices (iPod or future iPhone) — kinda sorta like the Samsung Upstage. The screen will be “force sensitive” much like the iPhone and could double as a keyboard or mouse, not just a click wheel.
As with most patents, there is no word as to if this will ever be on any product of Apple’s but it does create quite the buzz.
