A) The apps are compiled for a completely different CPU architecture (the iPhone has an ARM RISC processor, not an Intel x86 CISC).
B) The apps require a completely different set of operating system requirements.
C) Not even Macs can run apps unless they are compiled for the Simulator (which ones you download aren't).
All in all, no chance this is ever going to happen.
