The high point of Microsoft OS domination was 2004 with 54x. Since then its a drastic steep decline to 18x in 2010.
In 2010 people bought 18 PCs for every 1 Mac.
Like all statistics this one requires some deeper analysis. Consider that:
- in 2004 most computer users had desktops not laptops.
- in 2004 Apple was just coming up out of the rubble of near collapse, while MS was riding high on the success of XP.
- in 2004 people were not using phones and tablets in place of computers.
This is not to discount the gist of the story which is legit and interesting. Only to point out that it may not be a case of "people like Apples more than PCs", but more like a picture of market economics changing.
