You were kind of hard on Google.
Although, the list at the end seems to make a good point even though
it's not very realistic.
I think my list would be:
1. Free loaner phones of the first TI phone to Android developers. I
think that would do the trick for poor developers world wide, and
would not cost that much. With 2000 developers at 3 months each you
would need 500 phones. That would cost about 100K.
2. 1K in free AdWords for ADC participants that show AdSense Ads in
their Android Apps. That would cost 1.8 M - AdSense Revenue = ?
