Peas and rice.
Remember when Steve Jobs came back, one of the things he did was kill off a bloated and confused product line?
The iPhone comes in three models, the iPad (if this rumour is to be considered true) comes in five. Both use two different types of connector and the price difference between some iPad models is minimal, with the addition of the 8GB 5C, this is likely to be the case again.
Not to mention the frankly useless non-retina MacBook Pro I think some serious pruning is needed.
I'd crop the iOS lineup down to the Retina iPad Mini and Air (renamed iPad), 5S and 5C (possibly branded as iPhone and iPhone C) and iPod Touch (going up to 128GB)
But that is just my personal opinion.
How is a "non-retina Macbook Pro" useless?
