I remember rumors of Apple building a display that would allow you to dock your iPhone into it to use it as a computer. Then you'd just undock it and be on your way. That product never saw the light (or was never real to begin with). Motorola, however, has gone and built something fairly compelling - the Atrix 4G. I recommend looking at Engadget's thorough review of the Atrix 4G. The review isn't great but I think it is a step in an interesting direction.
