Popularity contest - Ubuntu vs OSX Lion vs Win7

A while back I played with Google Trends to compare Linux distribution popularity. Ubuntu was the clear winner.

In that post I also tried to compare OSX and Windows7 against the Linux supremo, but I think I didn't hit on the right search term for OSX.

I tried again today out of curiosity, and I think I got better results, though perhaps still not really reflecting the true state of the world (I'm sure OSX kicks Ubuntu's pants in reality).
