ARM Holdings has done a wonderful job of convincing the world that X86 is hot, expensive, and unfit for mobile. Many do not understand that Intel's "problems" in mobile have zilch to do with the CPU/x86 and everything to do with the fact that Intel is just new to this whole SoC gig.
During Hermann Eul's keynote, I couldn't help but notice an entire wall of Intel-based tablets. Intel has come a long way and I think over the next few years Intel will simply keep hammering away at this until there is no more doubt left that Intel will be here to stay in mobile.
