I'm the guy behind http://www.cheekswab.org, which seeks to educate people about joining the bone marrow registry. We also attempt to coordinate drives for minority groups in VA/DC/MD. Let me know if you'd like to join the bone marrow registry and enter the lottery to save a life.
It seems that the maps functionality was a non-trivial trump card when it came to the Android vs. iOS debate from the consumer side. I personally was even considering switching back to Android from my iPhone, partially because the nav functionality was so underwhelming.
What's the reason that Google would go ahead and bring that functionality to their single biggest competitor? Is it just a matter of showcasing their own technical capability re:maps (relative to Apple's incapability)?
