A lot of what people are saying on the subject is very doom and gloom, mostly with little actual understanding of what the TCG is doing.

There will be security benefits, and there will be no locking in with regards to any OS or software. You can even run pirated software and media still... you just won't reap the benefits of TCG if you do this. The benefits are of course access to new media with TCG based controls (until a hack comes out, and I see no compelling reason to think a hack for this should be long in the making) and the increased security through the MAC like controls and versoning controls.

Remember, all these hardware approaches do is divide the system up into three levels. Trusted, Assured, Untrusted. Untrusted is still completely at the users discretion as far what software and media is used.
