Even if Apple came around to using Intel, I don't think they will not announce it during their earnings call.
And being Apple, they will mention it in passing or have a brief comment when they are finally ready to make the change. Apple is intensely focused on promoting its own brand, not Intel or any other supplier.
It would not surprise me. They are already going into Android phones. And the Intel Phone chip benchmarks are shown to blow away the best ARMH based chips. Android phones have about a 20% greater market share than Apple too. Apple is certainly watching, concerned, and interested.
Ok .. i may be trading on luck .. but i am not technically stupid ... Intel will never beat ARM ..or invade mobile devices .... Have you seem the power foot print of ARM and roadmap they have... period.
