The fact that Google is, on one hand, creating great applications for iOS and, on the other, fighting tooth and nail for market share against it makes me wonder if the company is divided into two factions, with a battle raging between them over its future direction. On one side, there’s the group who want to promote Android as a coherent product, and beat Apple into a pulp with it.
On the other side, there’s the “Pragmatists”. These are the ones who realise Google makes its money from advertising, not directly from selling products.
As Ian points out later, Google’s iOS apps have to be good. They’re a company that makes its money from advertising.
