Throughout 2008, Apple consistently posted higher growth than Windows PCs. Thanks to this trend, Apple skyrocketed to third place in total quarterly sales. However, in Q4 2008 the first signs of trouble appeared as Apple fell to fourth place as its growth slowed.
Windows PCs, on the other hand, saw sales increase by 13 percent. The revenue ended up being virtually flat, though, as much of the growth was attributable to the burgeoning netbooks sector which features low-priced machines with low profit margins.
