Apple has a strange knack for adding and omitting iOS features between devices in an almost arbitrary fashion, with some apps and elements present on one, missing from another with no particular rhyme or reason. For example, the iPad doesn't have the native Stocks app present on the iPhone, and while this isn't too much of a big deal (as well as a slew of apps, there are many ways to search on line for the market trends, for instance), it remains a bit of a head-scratcher.
