Yes, I agree with that post that the USian pronunciation as given there is better than the British one. But Jobs' rendering of the American pronunciation also sounds wrong to me because the final syllable doesn't generally rhyme with 'wire' as I've heard most Americans pronounce the word.
It may be regional. Jobs grew up in Mountain View and I grew up in Santa Clara, just a few miles down the road. My parents and teachers always said something resembling "jag-wire" in pronunciation.
That makes sense to me. Ahr/ire is a pair that gets swapped or blended in other American accents as well, after all! Many Southern accents basically do the same kind of blending but in the other direction.
