Well, then at the same time it wouldn't count sales through Dell's website or HP's website, etc. I haven't bought a computer from a retailer since my first one back in the early 90s. Since then I have always bought PCs online directly from the manufacturer, but according to what you are saying those sales would not be counted. If that is the truth, then you are right about the numbers being pretty much irrelevant. However, they are irrelevant across the board, not just in the case of apple devices.
Sure. But Apples retail sales are enormous. All their stores are the most Sales per square metre everywhere in the world. It's more than double Tiffanys ( which have half as many stores )
I prefer to buy from the store as you have a simple point of contact to take it back to if it goes wrong. Apple are a little lacking in that. The online and retail operate as completely different streams, which is annoying.
Personally I think these figures are massively skewed in all ways.
