They could definitely afford to buy Yahoo and its whole suite of services, including search. But I don't think Yahoo has anything Apple really needs. Apple sells computer hardware (and you could argue that an iPhone is just a pocket computer). They aren't a search company. If they wanted to hurt Google, buying or rolling their own search wouldn't be as effective as just supporting Bing. Apple and Microsoft have both been at their best when working together, and Bing is nearly as good as Google, despite what some Google fans say. (I consider myself a Google fan, and I respect what Bing has done.)
Really, if you don't like Google (search), get the Bing app. It's very nice, and I think it's nicer than the Google search app. Since I use Google a lot, I search with Google on my iPhone when I want the search saved, and Bing when I don't (it has a private mode, which I leave on). So, like, if I want to search something health related, since I use Google at work, I don't want my job to know I searched that, I use Bing. Nothing wrong with the Bing app at all.
