As one of the most-anticipated gadgets of all time, the iPhone couldn't possibly live up to the stratospheric amount of hype that preceded its launch. Apple's hero product does, however, open up a new era in cell phone design. While the iPhone wasn't the first touch-screen phone to market, its sleek form and intuitive multitouch technology gave it the edge over its predecessors and most of its successive competitors. And with its integration of Apple's CoverFlow browsing interface as well as its Safari-based support for third-party apps, the iPhone's innovation went beyond its head-turning hardware. Look out for more music-playing, Web-enabled, touch-screen cell phones in the year ahead.
