Subtract five hundred from that.
From what I understand, they link to the user's eyeballs to prevent this.
Apple Computer's draconian control over its hardware makes sense when one is reminded about where that hardware is manufactured. Apple Computer is one of the few companies, of which I'm aware, that manufactures in China without being screwed over; it's able to do this because each part is cryptographically self-identifying, which prevents the so-called third shift, when a Chinese factory simply continues to produce parts and product well past the contract with the Western company. I believe I've read somewhere that some of its security co-processors are manufactured in the United States. Anyway, if Apple Computer only gives so many cryptographic secrets for so many parts, and all parts are authorized over the Internet by Apple Computer, then extra parts can't very well be manufactured like this.
Apple Computer controls the magic software, and that's the special edge it has which other companies lack.
