I am really curious what will happen to applications like Steam and similar. Will the Mac suddenly find itself in the same restrictions as the iOS App store? Will there even be a separate Mac App Store? Steam allows for users to apply activation keys paid for outside the client, normally these are sold directly by the game developer but can be the result of a give away. Can that happen in the current App store? The promises of better performance and all are nice but I am waiting to see if the walls come with it and will Apple pass the savings on to the consumer or lay claim to the increased performance as the reason prices stay the same or get higher.
