iPhone be a Lifestyle Companion

Idea to make the iPhone still pervasive than the iPod is One of the most recent Apple patents seems to be a new Nike + iPod system, with the iPhone as "lifestyle companion." .
The iPhone's built-in accelerometers and smartphone functionality, not to mention Apple storage capacity makes it an all-round gadget does not seem like a crazy idea. The extension of the idea even further, Apple plans to use the camera as a calorie counter iPhone kind to scan the bar codes on food, which, when Apple adds a camera to the iPod touch, it is only reasonable to expect that it is a lifestyle companion. It is definitely a good idea to me, and hopefully a new and portable hardware comes with the implementation.
Of course, these being patent applications, there's no indication as to when we might actually see such a system, but it sure seems a good deal more likely than some of Apple's other ideas.
