I think Intel, like Microsoft missed the big move to mobile.
Intel want x86 on the phones, since there are so many developers out there used to it, so many tools, so much software that would only need a small tweek.

I'm not sure about that. ISA is an implementation detail, a popup in your IDE.
Any existing Windows or Mac app that needs to go mobile will in the least need an interface overhaul (true for iOS and WP7) and at most need to adopt completely new mobile APIs.
