Peter Gutmann wrote a nice paper called "A Cost Analysis of Windows Vista Content Protection" in which he describes the Windows Vista's built-in content protection mechanisms and the considerable costs which are caused by these protections.

I'm going to quote several interesting sentences of his paper:

Providing this protection incurs considerable costs in terms of system performance, system stability, technical support overhead, and hardware and software cost. These issues affect not only users of Vista but the entire PC industry, since the effects of the protection measures extend to cover all hardware and software that will ever come into contact with Vista, even if it's not used directly with Vista (for example hardware in a Macintosh computer or on a Linux server)
