The reason Apple dropped model numbers with the iPad has seemed obvious to me for months: because they’re going to be selling the current “new iPad” alongside the yet to be announced iPad Mini.
Think about it, if Apple kept the model number then consumers would have to choose between the iPad 3 and iPad Mini. What would Apple do for the next version of the iPads?
Smart. And he makes a good point about the implications of the new iPhone being named “iPhone 5”.
