Edible Apple

From tkcodesharing:

So the problem is that as it seems, we will have a lot of different devices, with different configurations. Some will have touch interfaces, some will not, some will have a D-PAD, some will have trackballs, some will have acceleration sensors and so on…

That increases the amount of time and resources a developer has to use in order to make his game playable on most phones. The same problems that drive a lot of PC game developers to game consoles.
