And not of the "beta coming in Fall" kind, the check-back-in-ten-years kind.
If, say, Apple was also presenting such pre-demo quality stuff, they would have flooded the media with BS. E.g they could have shown their iPad prototypes in 2004, in a similar crappy form.
Google only presents this half-baked shit to show us it "innovates". I'd rather know if they can deliver.
I'm not sure Android is a good example of "Google making their money from usage".
For one, have the Android development costs been recouped even? Including the Motorola buyout.
Second, the more successful companies (Amazon with Kindle and Samsung, which is 95% of all Android sales IIRC), are either already having or in the process of locking Google out of it. The Fire's already doing it, and Samsung is investigating it's own path there too.
And if they could replace the web search to something else, they probably would -- but there's nothing much at the moment, which is why even iOS using Google as the default.
