Apple has 10% PC market share but take a large chunk of the profits.But this is US numbers, what's Apple worldwide share and correlate that to its worldwide profit.Market share for the sake of market share is pointless.
I believe your point was to remove Tim as CEO but give him less responsibilities.That's like removing Belicheat from his Head Coach job and turn him into a Defensive coordinator. (Side note: he should stop cheating).
"Normal" people don't post on tech blogs. So you are not an ideal example of the masses.Why would anyone replace Tim after a record quarter? Define "too much". Tim is doing what he has been doing for 4+ years. Apple hasn't suffered.
