Is there a good article about paying for upgrades?

Hi,

I am looking for a good article about why you have to pay for iTouch upgrades and not iPhones.

It comes down to accounting, iPhones are a subscription based revenue product for Apple and the Touch is not.

This article is a little old but explains it pretty good.
