The problem is that you (tech savvy customer) expect things like upgrades and revisions because you understand how your device works. The hardware components are static, but via advances in software, new functions can often be integrated in for no additional cost. You do this all the time with your computer whenever you load a new program into it. In your mind, the phone is a tiny computing device that should fit that model.

Unfortunately, the business types don’t see it that way. They see the devices they sell as complete units (partly because they get promo units early and never really think about things like upgrade costs). To them, the devices are magical and filled with delightful elves that do your bidding. To them, additional features must have cost associated with them (possibly as a revenue point).
