An interesting view with respect to the VISTA's content protection scheme.

Quickly skimming over this document, it looks like a piece of
journalism rather than a "cost analysis" it claims to be. Many of the
things it mentions fall into the "you don't pay for what you don't
use" rule, and I've got the feeling they were mentioned simply for the
"this is outrageous!" effect on the casual reader. One such thing is
his point about echo cancellation: If you don't play DRM'd content,
you won't incur this penalty. Besides, this penalty is part of the
kernel code, thus something which you incur by using Vista or other
DRMing OS, so it doesn't cost a Linux user anything.
As to the kernel API signing, where does he even get this nonsense?
From following NT device driver developing blogs, I've heard
absolutely nothing about this, which is strange since Microsoft badly
wants driver vendors to be ready for Vista.
If anything, I was expecting digits showing the performance
degradation (if there's anything like that) from running in a
hypervisor or with the newfangled IO-MMUs. Instead, I've got someone
running a smear campaign on Vista. ... Next!
