You can't really turn launch weekend into a case study. Above the normal level of buyers and those drawn in by advertising, you have people who keep track of dates to buy a new device. This is not to say they're not doing well.
The debate is generally over where they will find more buyers. Without subsidies, an iphone costs as much or in some cases more than a low budget PC. This represents price territory they covered anyway. They just moved some of the costs around according to the teardown. I suspect they reduced manufacturing cost or the need to purchase costly equipment somewhere, but I don't see where you have enough information to draw an unbiased conclusion.
I'm not trying to do a case study. Just observations from first weekend sales.
I'm not sure what your second comment about price compared to a computer and the teardown have to do with my comment.
