Thanks. I hadn't seen that when I asked.

I think this is why Apple pushed iOS apps to 64-bit only when they did (64-bits is not a requirement, but the sooner creative apps support it the better.)

No, I expect there are reasons to have different interfaces though I can see all the layers below the surface could end up the same.



It seems this is a combination of:

* Taking advantage of the iPhone/iOS app ecosystem
* Maintaining purchasing leverage over Intel
* Apple hedging their bets (they can do both for a while)
