Why would people actually buy this new OS? Because all the computer illiterate people who don't know a thing about computers will buy it - people like my mother who doesn't give a rip about the OS she's running. If enough of these people buy computers with TCPA inside them like Microsoft's future Palladium, it will turn into a monopoly and everyone will practically be forced to buy one.

Say you have Linux and write novels for a living. You have three friends who have TCPA compatible machines. There is no way for you to share your novels with your friends because TCPA will not accept your file. So, you have to buy your own TCPA compatible computer.

You have to remember who we're dealing with here - Microsoft.
