My response may be late, but here goes:
I've been exposed via work and academia to both the iPhone and Android platforms for the last year. I find two glaring flaws with both platforms that will limit, if not prohibit, viable entry into the biggest mobile market -- the business enterprise. Oddly enough, the flaws are opposite sides of the same issue: enterprise compatibility.
iPhone - Because Apple exerts ultimate control over what app makes it to the App Store, AND the app must be available to anyone once approved, IMO, iPhones will never become the defacto business mobile device. I cannot envision a business that would willingly expose it's source code to Apple's scrutiny. Nor would I want my "internal use only" enterprise app available for download by anyone in the world. I find that scenario laughable.
Android - OTOH, because Google (and now Oracle, too) exert no control whatsoever on app development, anyone who wants to, regardless of ability, can slap any old app on the App Market whether it works or not. I would not want my app lost in the confusing mix of slap-dash, teenage tinkering, malicious mongering developers. Would you?
However, the tie goes to Android because developers are not compelled to submit their apps to public access in order for them to be distributed.
Any other platform is either niche or passe'.
That's my take on the issue.
