Surprised. I thought Apple would sell more, specially in USA, where the price is not that high because of the purchasing power
50% of consumer spending is by the top 10% of consumers, with that 10% generally being Apple ecosystem people. Anyone with ecommmerce stats can confirm this, Apple consumers just shop and consume more, particularly at the high end.
This gives the impression that Apple are even bigger than they are.
Apple might be the top laptop seller in the US, not sure. There are more people using Windows, even in the US.
