There are two PC makers that actually have any sort of growth year-over-year: Apple and “Others”. And remarkably, Apple’s growth is bigger than even “Others” — all the PC makers not in the top 5 — combined.
If the current trends continue (as they have been for some time now — look at the chart in the MacRumors post), Apple is poised to become the top PC maker (in terms of shipments) in about 3 years.
But before that happens, such a title will continue to matter less and less. What will matter is who the top tablet and smartphone makers are. And even more, who is making the most money from all of this? Apple has already won.
