Apple aren't a daft company: They know where to invest their money. If they thought Qualcom (or Intel) offered them a better solution rather than designing their own, Apple would take it. The fact that Apple have taken on the massive overhead of designing their own silicon and still come out with a design that it as good as, or better, than Qualcom/Intel speaks volumes.
If Qualcom want Apple's business they should offer a solution that Apple couldn't resist. Actions speak louder than words. Qualcom are just throwing a tantrum as they no longer have Apple by the *ahem*...
