The box says Motorola. That means they signed off shipping it. Even if any problems with it can be placed firmly at Google's door, it still says Motorola on the box. I think that was the previous commenter's point.
Fair enough. Motorola definitely shares blame.
But at the end of the day all that is Android ends at Google's feet. Why play games with holding back the 3.0 source if you don't at least feel you have some responsibility for how Android launches on tablets?
The device has both logos on the back, and they're the same size.
How are you actually arguing with this point? Is it just because this is the internet and fingertips are a renewable resource?
