A Big-Picture Look at Google, Microsoft, Apple and Yahoo

It would be interesting to break this down by revenue, and compare what each company is actually making on each category.

Google would be dominated by search, which would likely be a fraction of the other companies business. Microsoft would dominate office suite and and OS while the others would be a non factor. But the rest of the categories would be pretty interesting.

This is a key part of Microsoft's strategy currently as well as moving forward as evidenced by integration in their upcoming mobile phone and most likely other platforms.
