Google doesn't just make money off both iOS and Android - they make MUCH MORE money off iOS than Android, at least twice as much. [1]

But they don't control iOS, so all Android is is a hedge in case Apple tries to disrupt mobile search somehow. I honestly wonder if there's any tension at Google between the search team and the mobile team, since at the moment Google is flogging something directly against the interests of their cash cow (search).

Microsoft is Google's direct competitor in regards to mobile search...or search in general for that matter. As for Apple, I don't see them entering search because search, in general, suffers from the level of curation Apple tends to association with its brand.

That and software-as-a-service just isn't Apple's business model. They just want to sell you stuff.
