Microsoft is no slouch (especially compared to Google), but these charts seem to imply that Apple still has the more diverse revenue stream:

Apple's also not really a software company.

Still, even if you ONLY look at Apple's software revenues, I suspect that Apple would turn out to be more diversified than Google. :)
