As often is the case apple products slowly evolve rather than change in a revolutionary style. The reason is that they don't compromise on what they see is their perfection until it has indeed dated. Across all their products.
What do you think of the new iphone 5 ?

I would be happy to own it and there is only so much you can do with a phone shape though I love the pebble shape of the 3.
I just think they could have done a bit more..
