You are thinking of Android as just an OS for consumer mobile phones. You don't always need Facebook to run on it for it to be useful. It is a great polished Linux distro that can find a lot of uses. Think of it as a specialized Linux without the GNU user space. It has a full rich and powerful API without relying on google. Also device integrators are free to fork away from the base APIs to add their own functionality in the same way google has. If an app wants to be portable, they shouldn't build against these proprietary APIs. This isn't a unique problem to android and doesn't make the source any less open. What I love so much about open source is that once a project is out there it can take on a life of its own. People can/have/will start cramming Android in places Google would have never expected. It makes a great base for POS systems, high end touch screen vending machines, in flight entertainment consoles, and any number of other things I can't think of but I'm sure the community will.
