Besides the fact that the bricks probably cost Apple 50 cents apiece.
50 cents a piece? So since you’re stating that that as ‘fact‘, post a direct link/source showing that it costs Apple $.50 to manufacture a charging brick for that cost. (FYI,Which is actually a forum rule if you claim something as ‘fact’, you are obligated to follow up with a source for your claim.)
Also, I would suspect your claim is completely off, as you’re not factoring manufacturing costs of materials and labeling, T&E, ect.
If I were an Apple newbie and bought a $400 watch, I'd be pissed to not get that charging brick because who the hell wants to make a trip to Target.
Sure, that could be an inconvenience for someone new to the Apple Watch. But Let’s not make it sound like somebody had so much burden travel to a store, when they can easily order one off-line just as a secondary option.
