If you thought that was a lot, wait until you see what Google will have to pay for primary placement in Safari. I don't recall when that deal is up, but you can bet that Apple is going to be all too happy to stick it to Google for pilfering the iphone design for use in Android hardware.
Apple has a tremendous thing going with iPhone and IPad sales. They're none to happy that Google is trying to rock that boat. I expect Apple to force Google to pay dearly for placement, Apple will be just as happy to switch to Bing.
btw, if you thought Bing's existence was a waste of energy, it was built for exactly this kind of forcing costs up on competitors. It doesn't have to be widely used, it just has to be a credible threat so Google is forced to pay more than it otherwise would have.
Does a surprise increase of 300% to Mozilla mean that they are going to be able to hire more developers, and build/iterate faster?
