Honestly I suspect Google is trying to grow a third party ecosystem. By that I mean they leave obvious problems half solved or unsolved so that someone else can come along and do a really good job of it. Cyanogen, GetJar, Dropbox, Opera, alt home screens, etc. By doing a 40% job Google leaves easy victories for third parties. I expect the 'end game' is a better OS with a healthy ecosystem and is not dependent on Google. Remember Google got into mobile to protect their ad market. A healthy competitive OS ecosystem would do this all without massive long-term engineering effort. Why build an OS and ecosystem if all you have to build is the OS?
