Summary advancement of the new OS:

What is interesting in my point of view, is the new business in-apps purchase model. With the subscription features, developer will be able to introduce additional features of the application and end-user able to spend according to what they require or demand. For example, like game application, developer can introduce additional stage when user reach certain stages of the game and with the push technology it allows developer to push message in the middle of the game to allow user to buy the additional stage if the user demand too. Interesting.
