I am always in a war when it comes to iPhone vs. other phones especially Android based. Most of the people arguing in my opinion argue on the wrong factors but that is for another post in the future. But no matter what device you use (phones or tablets) or the platforms (iOS/Windows/Android/Nokia's OS), the near coming future would be about making the apps/platform/OS just work more closely and more easily with each other.
When I am giving you a demo on phone/tablet or I am trying to transfer some information to you I just want to get the work done without arguing about how our devices are incompatible and use different protocols of talking to each other. The apps that can do this more transparently on the dissimilar platforms will come as winners.
