The iPad and the iPad mini are the same platform.
If you write an app for the iPad it will look and function the same on the iPad mini... only smaller.

Yeah... Apple has really stuck to the one phone per year idea since 2007.
It's interesting that they are breaking tradition and announcing two new phones in a couple days. Obviously they feel comfortable doing so.
Now let's see them branch out a little more and offer a greater range in their smartphone product line.
This is the same company who offered 4 different iPod models... surely they can handle a few phones.
