The iPhone is clearly capable of doing this. I also wish for your smartphone to become your main (and potentially only) electronic device. Just dock it to a monitor to use it as a desktop pc, dock it to the television to watch movies or play games. When travelling anywhere all you would need is your phone. But like you say, Apple has no incentive to do this as it wants to sell iPads and Macbooks. Hopefully in the future this happens.
