General computing platforms are held to a higher set of standards than console devices. If Apple wants to call the iPad a computer, and market it as a replacement to traditional desktop and laptop machines, well, it is time for Apple to start treating it like one.
I don't think US antitrust law makes any such distinction.
Personally, I don't see why a general computing platform cannot be locked down, complete controlled by one company which is engaging in extreme discrimination of its suppliers and business partners, and even their customers.
