Let me say this: 24 iPad models does not sound simple.
The iPad mini needs, three storage sizes, two wireless models and two colors — that’s just 12 models. Apparently, the secret second 12 are updated iPad models with the new Lightning connector.
At first I thought it would be odd for Apple to release an updated iPad out of cycle. But maybe this makes sense. The iPad 2 will go away in the next iPad cycle and the current new iPad will be the second end model while the new new iPad will take its place among the top end.
