? HP had a 20% worldwide marketshare for PC sales in the previous quarter.? HP sold 16M PCs worldwide.? Apple sold 3M PCs worldwide.? Apple would have to sell over 5x as many Macs per quarter to only match HP.? That means the $3.95B they made in Mac sales would be $21B in Macs while keeping the same business model that is working for them.? Microsoft did under $13B for the same quarter.? Besides being considerably more than MS, that is MS? entire business v. only Apple?s Mac? and it?s still over 3x smaller than the Windows unit sales for the quarter.
