Peter Gutmann, a cryptography expert at the University of Auckland, has written a Cost Analysis of Windows Vista, where he discusses how the "content protection" and trusted platform features described in the Microsoft Windows Vista "security" specification will destroy reliability and innovation in the computer hardware industry, as well as make life miserable for us, the users.

Doomsday scenarios like this were brought up when Microsoft Windows XP was about to be released, and though it was enough to make me switch away from Windows to Linux, most of the concerns did not materialize. I don't know if Vista will be any different of a situation, but if the notion that they definitely want this kind of control (irrespective of whether they can actually do it, or whether the market will let them) doesn't make anyone who enjoys using their computer want to switch, I don't know what will.
