Well that was the original android phone idea. Get a hackable open device that you can write apps for your self. Even attach third party hardware to it for extra functionality with lots of customisation. But this idea has mutated quite a bit.
I fully agree with it. But I think Google also understands that the platform is unatractive for businesses. In my case I just don't do Android app because I know it is easy to just take and hack.
