Personally.. I'm always a fan of choice. Just because a 5" or 7" device isn't suitable for everyone doesn't mean it isn't suitible for anyone. They offer multiple choices in the mac line because they realize that one size does not fit all. I could see the same case being made for iOS devices.

Exactly. Apple is turning its attention more to mobile devices than their computer lineup. They have 11, 13, 15 and 17 inch variety laptops, so why would anyone think they will only ever have a 3.5 inch phone and a 10 inch tablet. There will be more Apple mobile devices and much sooner than later.
