Only if you actually use GMail. I wonder what percentage of iPhone users use GMail on their phones vs. other email services. I don't use GMail. My calendar syncs with my non-G calendar and my Mac. Ditto for contacts.<p>In what respect does Android integrate these features better than the iPhone does?<p>The one thing that sucks on Google Maps is you don't have access to reviews (or at least in no way that I can determine). At least they show subway stops.<p>I think success here is probably determined by number of hardware units sold.<p>PS: Apple doesn't do maps.
