Its true they're doing this because they see the success of the Apple store, and its true this is scary, but I do hope for the sake of Microsoft that they succeed :P
I say this because I'm not an Apple fan, and seeing people pay so much money for Apple's stuff makes me a tad angry, but hey kudos to Apple for their success. What I want to see is some competition to the Apple store and this is also a good opportunity for Microsoft show its true colours, which I don't think its doing presently.
