@Phil: I don't get it
The examples you have given are either games consoles or appliance electronics (in the case of blu-ray). They are designed for a single purpose, and subsidised by the manufacturer (in the case of games consoles), with a levy on the software supporting this subsidisation.
The iPhone is not subsidised by Apple (in the UK it is usually subsidised by the supplying Network provider, again supported by income from your monthly contract), and is designed to run applications. It is pushed as a device that "has an app for that". However, if "that" does not fit in with Apples view of how the iPhone should be, it simply will not be approved.
How many other "smart" phone platforms can you mention where the owner of the device is not the one to say what applications they can use on it?
How many other computer platforms (and we have been repeatedly told that a smart phone is a portable computing device) can you mention where the owner of the device is not the one to say what applications they can use on it?
Now do you begin to understand?
