One point I ignored in all this, is the environmental aspect. With a sealed product, Apple doesn't have to worry about an idiot customer replacing the battery and disposing of the old one in an environmentally damaging manner. Our environmental laws are fairly lax when it comes to other places in the developed world. I wouldn't be surprised to see the day come when electronics with rechargeable batteries will be required to be sealed from customer tampering.
That is one good thing, but they sure are charging a lot for the service which is what has people berating a company before said company even has the product available for purchase
