Apple is entirely capable of pursuing this kind of model itself. This could be either the carrier financing model, with the cost of a phone spread over a 12-24 month period, or an “iPhone for life” program under which a customer pays a fee each month to always have the latest iPhone model. Under the latter model, the older device would be handed back to be refurbed and resold when the customer gets a new phone. Apple has the deep pockets to fund such a model, and it would help to smooth out its revenues across the year too even as most of the upgrades continue to happen in the third and fourth quarters.
In short, the Apple SIM is a step in the direction of a new relationship between Apple customers, Apple and the carriers. But in order to reach its full potential in the iPhone context, Apple needs to make another significant change: allowing customers to spread the cost of owning an iPhone over a longer period. Only if it does that will the Apple SIM be truly disruptive.
Fascinating idea that I think would be a tremendous success. Imagine the possibilities for developers knowing that most iPhone users out there were using the latest and greatest hardware.
