Let me be simple since you didn't investigate the TCG (TCPA).
There is a crypto-security co-processor that resides on the motherboard. This co-processor has flash built into it. It is not removeable and it tamper-resistant.
Currently you turn on the computer and you authenticate to the OS. That does not make for a very secure computer.
With the co-processor, you authenticate to the machine (the BIOS).
You can store anti-virus applets in the flash (read as revenue stream).
You can store many other applets, some that we can't even think of yet.
That is a tremendous revenue stream opportunity. One sells the applets.
The applets are moved around by a server/authentication system.
There was not much info on this a year or two ago, but I think you will find some now if you choose to look.
