The US developer culture seems to be very Apple-centric, so Google is fighting an uphill battle in US, and I don't think that's easily changed with a few marketing bullet points. In US, if one has a Mac (which most developers do), it's almost guaranteed to want an iPhone, too. If one has a Windows machine, maybe they'll want an Android phone, maybe they won't.

Of course, Google should still do more to promote Android to developers. However, it should be much easier to get developers from most of the other countries, since that's what the vast majority of people use there.
