Made an edit in the OP based on Forbes 2000 list (2008). If someone has the current data, please post these.

Really strange that Nintendo has passed Sony and is closing in on Apple. They have only 4000 employees and are now the company that earns most per employee.

I apologize if anyone was mislead. Coming from the academic world I just assume that outrageous sources are automatically treated with appropriate skepticism and we frequently use them as a vehicle to start a debate and invite inquiry. If I overshot the market ( a failing I would then share with Sony) I will be more careful in the future and give blatant warnings instead of hints.

Since Market Capitalization is suposed to be straight forward, I have no idea why it's not consistent but Goggle Financial has some other data which is interesting. And no disclaimer is necessary as I believe these figures are quite accurate and consistant with other sources.
