15 years ago Microsoft held a monopoly on desktop operating systems. Apple is nowhere near a majority in the SmartPhone market today. I think there's very little chance they will ever hold that type of dominant position in the SmartPhone market so whatever they choose to do with the iPhone & App Store doesn't really impede the consumer's ability to choose an open platform. I think choice is a good thing. If someone wants an open platform they can get it. If someone wants a nicely packaged, but extremely functional and trouble free, platform Apple will sell it to them.
