Why are Microsoft's profits from Windows excluded from the numbers while profits from OS X are included? Why isn't MS considered part of the PC industry?
Or because Microsoft doesn't make "PCs"(well not really) and Mac does. But MS does make devices/phones/Xbox (which is a PC in console's clothing).
Edit: I'm glad that they at least lump it in with PCs now though... It used to be that people would get angry if you called their Apple Computer a PC. But now that they are just Intel PCs running OSX it seems hard to debate.
