The reason Apple is so profitable is because of the iPhone. The Macs aren't bringing in all that much money and I'm postulating that Mac will lose a lot of market share because they ditched the x86 architecture. Although revenue for Mac is still increasing (most likely because they're making even more profit by using their own CPU) the sales are already softening.
