I read that article and found it rather interesting. Well to me no matter how you take those numbers, the one fact no one can deny is apple's marketshare is improving by some amount.
I remember back in the windows 98 days. When people here in Australia camped out for ages for the midnight launch of it at stores. And people were actually happy to own their PC and were quite vocal about it. And I saw them everywhere.
But now I don't hear anyone saying their PC is their lifesaver and best thing they've ever bought. They mostly just use them cause they have to or always just have. And the same goes for the big and small screens (read the cinema and TV). I see now days so many movies and shows with Apple products in them.
I don't think PC's are doing anything different to the old days. The same standard of hardware and software is coming out from them as in the old days. But that's the thing. They stayed the same, got complacent. Never really bothered to try for something revolutionary or special for their customers. Whereas Apple are always on the ball. Last years standard of products and running things are no longer good enough anymore at Apple. They always must be better, achieve more, do more etc. Even if there is no one left to best, they go out to beat themselves. Always striving for a new mark.
And I think MS need to adopt this policy if they are to survive. Riding on old success can only last for so long.
Apple are not perfect either mind you. But I think they are closer to their goals then MS are currently.
