Well, I'll be a bit worried knowing that this will probably require a TPM chip...
But as was said during the summit, the plan is to be able to disable the DRM / signed image boot...
I wonder what it'll block?
How will extensions / mods to the OS be handled?

I hope we get the proper access to the chip too so we can use less futile tech than DRM like storing our own crypto keys and such...

In the mean time there is no magic bullet, it's been a cat&mouse game for the last 25 years, people will put serial numbers, other will copy or crack them, and then level 2 ! ... ;-)
