The issue being phones are horrible to do any actual work on. People search more, yes, but for things like maps, not products or anything else search engines might conceivably make money on advertising on with the main exception being simple stuff like "nearby restaurants". Nobody wants to, for example, buy a new TV on their phone if they can at all help it; they'll do the research on a real computer and the purchase either there or instore.
