Reading patent applications provides happy bloggers with ample fodder for blue-sky speculation. I rarely report these what-ifs for the same reason that I avoid Japanese new-product introductions: it may not happen, or it may not happen here. But the San Jose Mercury News
uncovered an especially interesting what-if in an Apple patent application several months back, one that may affect the user interface of the iPod—revered by many as the Michelangelo's David of industrial design. Reporter Troy Wolverton explains: "The company had previously explored replacing the click wheel with a virtual one as part of a touch-sensitive display." As it has with the iPhone, touching off speculation
. "But now," Wolverton continues, "Apple appears to be looking at a third option: a touch-sensitive frame surrounding the display. Rather than click a physical button or press a virtual one on the screen, users would touch an area on the frame to operate their iPod." Needless to say, Apple didn't return the reporter's calls, and this cataclysmic ergonomic shift may never happen.
