Right but you are not understanding my point. He doesn't follow Mac because it's a small part of Apple's revenue. That is not the same thing as him not caring if Apple discontinues it. From a financial perspective he would care about whether Apple could replace that revenue. If it could, yes, he's not sentimental about any particular product. He's a financial analyst. Money is money. I doubt many analysts coving GE monitor light bulb sales.
And... that would make him not a very good financial analyst, because the real world is much more complex than a pie-chart and spreadsheet. No, things wouldn't be the same if you could replace the Mac with equivalent revenue. For crying out loud, this is a developer's conference. If the Mac went away, how would developers make the apps that drive the iPhone?!
My fear, is that Apple might have a bit too much of this kind of short-sighted thinking going on as well.
