When we are working, there are sort of two outputs. We’re building a Nexus device and we’re building the open source code. There is no way you can build the open source code without the phone or tablet or whatever you are building. You have to live and breathe the code you are developing.
You can’t build a platform in the abstract, you have to build a device (or devices). So, I don’t think can can or will ever go away. And then, I think Nexus is also interesting in that it is a way of us explaining how we think Android should run. It is a statement, almost a statement of purity in some respects. I don’t see why we would ever turn away from that, it wouldn’t make sense.
lunga vita ai nexus
