The same way Google looked at internal OpenMoko efforts and decided to just buy Android. Now the problem is Android is tied to company that gets all of its revenue through advertising. I just saw an article about how typical Android apps query location thousands of times a day to sell to advertisers. Google will never implement an Apple-like "Enable location" prompt. This is their bread and butter.
This is also why I think a Google robot will fail. It'll be too tied to advertising revenues and other privacy affecting services. People will be wary about the "spying" robot in their home and businesses and will opt for a competitors product.
I don't know -- a next-gen, armed BigDog is kind of scary.
