Thank you for reading this. I don't ask this rhetorically; I'm interested. Is there any reason why the second or third generation iPhone couldn't incorporte the infra-red or radio signal necessary, as well as the interface, to become your universal remote control? Likewise, is there any reason it couldn't incorporate the signal/interface necessary to run your lights, thermostat, security system, etc. like that X-10 technology (I believe) already does? Perhaps these are foregone conclusions, or perhaps there is already a smartphone that does this stuff; I don't follow it enough to know. But it seems to me that surely we won't have separate remotes, thermostats, home security interfaces, digital jukeboxes and telephones in five-years time. I like to think Apple is in the best position to create such a device. I appreciate anyone's thoughts.
