Unless, of course, Google is cooking up software to integrate web-based advertising into our mobile lives in a new way. This, to me, is where the greatest chance for something exciting to happen lies. Even though being bombarded by ads on your phone may sound miserable, it could be how Google aims to keep the cost of the hardware down. Remember, Google loves giving services away for free if it means more people will use them and be exposed to the fairly low-key web ads that come along with them. When plans for Android were first announced, this is where many people predicted Google was heading: heavily subsidized or even free mobile devices, with no direct tie to any network, all supported by ad revenue.
