I think the whole platform-specific app development issue is going to cause increasing headaches for the mobile platform developers over the next year or two. All these rigid policies and semi-arbitrary and unaccountable decisions to reject apps and locked up technical details just make it hard for serious businesses to justify committing the resources required to write native apps worth more than an iFart toy.
Maybe some will and they'll get away with it, just as right now Zynga are doing pretty well even though they're almost completely dependent on Facebook, but the average app developer doesn't have the highly valuable and almost symbiotic relationship that evolved in that case. Meanwhile, much of what apps do could also be done almost as well using web-based software, which can run quite happily on any modern mobile, can be developed at a fraction of the cost of targeting each platform with a native app, and doesn't carry any risk of lock-in or summary execution by random platform developer/app store employee.
