This is for brick and mortar stores only. I'd wager that if online sales were included, that the percent would drop significantly. I'd even say it would be less then 50%.
I think that is a case of getting your maths wrong.
Say they counted 1000 computers, and 91% were Macs. That's 910 vs. 90.
You'd need at least 910 PCs to get the Mac share down to 50%. In other words, you are claiming that only 90 out of 910 PCs in the >$1000 segment are sold in brick and mortar stores.
I don't think so.
It would be really nice if they reported what market share sub-$1000 computers have overall to put things in perspective. But perhaps that blows the headline drama?
There are numbers out about Apple's total unit share. The point is not so much Apple's enormous market share in the >$1000 market (which they could increase by changing the MacBook from $999 to $1001), but the average selling price. Apple makes 3 times more dollars per unit sold than its competitors. So if you take the market share in dollars instead of units, then Apple is in the top 3.
I love Apple, but i don't know how they can hope to continue being successful without addressing the lower end market more.
It works now. Apple makes 20 times more per computer than Acer (which is actually about 20 times better than Gateway and eMachines were). Apple defines success by profits, not by units sold.
