As much as I like the people at RIM, they have no innovation on the application side that can resist what Apple and Google are doing to them right now. Ask people why they have a Blackberry today and the answer will be: push email. Messaging was a great differentiator 3 years ago, but for iPhones and Android-based phones, this is not even a table stake anymore.
Operating systems that can accommodate a rich and vibrant developer community will allow the creation of many small innovative applications that will drive revenue for carriers, handset manufacturers and developers. The more revenue they will generate with the platform, the more new developers will invest in this technology. Microsoft's response will be interesting, since they would be the only other serious contender in this battle.
Control of the user is achieved through control of the device, network and content. Google is becoming quite dominant here.
