No, I don't agree with that. Remember the Motorola Razr? That was 'the device' to have, and Moto was almost completely out of the market within a few years. I don't expect Apple to rest on their laurels, but they have competitors gunning for them, and this won't be a market where everybody has only one device. This may not even be as homogeneous as the pc market. Just my 2cents.
