He's misconstruing what happened with Mini and Nano iPods. At introduction the iPod Mini only cost $50 less than the full-size $400 iPod, with less storage, and it was perceived as a pricing misstep until they sold a jillion of them. People couldn't get their heads around the idea that Apple wasn't selling a cheaper device, they were selling a smaller device. Some people still can't.<p>This lesson is not applicable to Apple's current crop of devices, because introducing a new screen size would throw a huge monkeywrench into app development. Anybody blithely asserting that Apple might do it to save a few cents on production has a credibility problem.<p>So, this post boils down to an assertion that Apple could allow manufacturing prices to dictate the size of a device, even though changing the size would have dire effects on its usability and market acceptance. Does that sound like Apple to you?
