Way to stifle innovation, Apple. incumbents and lawyers getting what they want, fantastic system ...
Innovation and theft are two different things. Forget the hardware and architecture patents - I'm sick of design being treated as a commodity that's assumed to be freely copyable, simply because it's a user interface rather than a hardware element. Just as many hours and insights went into making the iPhone UI as it did the physical device.
Maybe hindsight is just 20/20, but "slide to unlock" seems to be something pretty obvious.
