Trade off for what? It's a mobile chip. It's fine for what they are - and more efficient where they're needed - battery duration.
Don't tell me you're happy with "strong" Atom powered smartphones that can do 4 hours of calls and 2 hours of Angry Birds. Not a trade off I'd prefer.
Sorry, I was taking about laptop CPUs whereas you were talking about phones/tablets i.e. Atom. The fact that the article also flips between these hurts the discussion.
What chafes here is that Jobs is acting like he knows Intel's business better than Intel does. Same idea as the story posted earlier. Intel moves like a steamship because it's vastly more efficient (i.e. profitable) to make as few designs as possible and mass-produce them than it is to make a chip just to meet Apple's needs. Might be different now considering the number of phones/tablets Apple sells but it wouldn't have made sense at the time. "We tried to help Intel" ... what a douche.
Also, funny nobody quoted Intel here:
Isaacson also includes a rebuttal from Intel CEO Paul Otellini. "It would have made sense for the iPad to use Intel chips. The problem...was that Apple and Intel couldn't agree on price. Also, they disagreed on who would control the design," according to the book.
Now THAT sounds like Jobs/Apple. ARM would still be more power efficient but I'm 99% certain Otellini's speaking the truth here.
