Nothing is static. Apple dumped firewire. Each generation of iPod has wildly different input methods. Even the default meanings of the function keys on Apple keyboards and laptops have moved around.

Give it time, I'm sure Apple will release an iPhone that has something new or isn't directly compatible with a previous version in some way.
