I recall discussing the spec of an upcoming phone platform in about 2007 or so. It claimed to be 4x faster than the previous generation and there was much rejoicing. And at the same time the screen went from QVGA to a widescreen that had 5x as many pixels... And the camera from 2MP to 8 or was it 12MP. In practice, from a usability perspective, the new platform was slightly slower than the previous platform :(
