Congratulations on your new baby.

Working in the security business, paranoia is pretty
much a job requirement. "What's the worst that could 
happen?" is taken seriously.

The best that can happen with TCPA is pretty good -
it could stop a lot of viruses and malware, for one
thing.

But the worst that can happen with TCPA is 
pretty awful.

It could easily be leveraged to make motherboards
which will only run 'authorized' OSs, and OSs
which will run only 'authorized' software.

And you, the owner of the computer, will NOT
neccesarily be the authority which gets to decide
what OS and software the machine can run.

If you 'take ownership' as you put it, the internal
keys and certs change, and all of a sudden you
might not have a bootable computer anymore.

Goodbye Linux.
Goodbye Freeware.
Goodbye independent software development.

It would be a very sad world if this comes
to pass.
