Asus Padfone delayed, but does it matter?

Phone Arena is reporting that the Asus Padfone has been delayed (again) due to a shortage of Snapdragon S4 chips. The bigger question, however, is if a concept like this will be successful in the long run. I have to say that I think the ship has already sailed on the idea of a phone that fits in a tablet and that it may prove to be little more than a novelty. It is difficult to leverage the potential power of a tablet when the phone is the brain and it makes little sense in terms of power verses size.
