Oh, come on. Even the staunchest apple fanboy would have to admit it sometimes leaves off or under provides on features to give their products an upgrade path for the next year.
Exhibit A is the lack of a camera in the iPad 1.
(Betcha they're going to come up with a drastically better camera with the same physical dimensions in the iPad3, and call it revolutionary and magical. If they don't put in a better camera in the 2012 model, I'll believe it's not possible to do so, fine. If they do, you'll know that Apple marketing is calling the shots.)
Exhibit B is the 256 gigs of ram in the iPad 2.
The evil geniuses at apple marketing also find compelling reasons to upsell consumers to higher priced machines by artificially hobbling the base models.
Exhibit 1 is the paltry 2 gigs of ram in the 2011 $999 11" Macbook Air.
To a certain degree all companies do it, but-like all other matters-Apple does it better than everyone else.
