It's pretty obvious that more and more things are converging to the phone. We've already seen how modern smartphones have markets like the point-and-shoot camera and portable music player. It makes sense to carry around one device that does as much as possible. And I love the extension of the smartphone into these home automation areas (though I realize locks have a significantly greater market than just that). What troubles me right now is the fracturing, but that's inevitable in emerging markets. It would just be nice to have a really great product line that I could use to unlock deadbolts, open my garage door, automate my lights, control switches / outlets, program my thermostat, etc.
