My experience is that where they directly make money, they're very responsive -- their adwords team has been very responsive to us, a small startup. And I bet they're very responsive with the big OEMs.
They don't have much financial reason to put energy into small Chinese OEMs. Google wants to control advertising, and as long as they have relationships with the folks selling the premium handsets in china, they have most of the advertising $$.
I'd agree. On the ad exchange side, their customer support is the best in the industry. But then a lot of that DNA comes from DoubleClick where they have always needed to provide sales and support services to a wide variety of customers and partners.
