I'm not sure how I feel about it. I can see Apple wanting to at least replace the contact style push button with something a little more robust like a capacitive sensor. The button that is on there now is a wear component that will fail at some point, so taking that means of failure away from the device only makes sense. I think Apple is just playing with some ideas right now. In some shape or form I believe the home button as we know it now will be gone on third generation devices.
