iOS screen fragmentation points to a shift in app development

We’re going to see a big change in a certain type of iOS app—the one designed for the device….In a sense, this could be a good thing—freeing up iOS from the constraints of specific screen shapes opens up developers to whatever Apple throws at them next and should also make apps simpler to port to competing platforms. But it also impacts heavily on those tightly crafted experiences that were designed just for your iPad or just for your iPhone.

With web having been down this road for a while, it will be interesting to see native apps designed in a more responsive direction.
