From Fraser Spiers:
All of these are available on iOS now. That is - more or less - the entire Google services suite fully accessible on iOS. There’s seemingly nothing that Google is obviously keeping back for Android exclusivity. That’s not what Android is about for Google.
This is a concise summary of the current state of our new imagined holy war. I do think Fraser misses one persistent conflict: privacy. Apple has been strongly asserting that they do not want or need to collect user data. I think this will continue to be a conflict with Google’s business model.
