MM: "[...] And those are things and innovations we're able to build [...] because we have more freedom and flexibility there. And we do really like Android as a platform and Google Maps for Mobile by far shines the most on Android because we can do so much more with features. Similarly indoor maps: Android is the platform that we're able to launch that on.
"Is the idea though to do it on Android first and hopefully matriculate it out to other platforms?"
MM: "Well it certainly is the case that we love to showcase these new technologies and things that we can do on Google Maps for Mobile and the platform that we have the most flexibility with is Android. If you look at Google Maps for Mobile it is far ahead on Android."
(I hear 'Android is the platform we're able to launch that on' and 'the platform we have the most flexibility with is Android' and wonder if by able and flexibility, she is implying more of 'in a business sense' than from an exclusively software development perspective.)
