I came across this site the other evening. It is an extremely comprehensive missive with respect to the security aspects of Vista in general and the DRM in particular. By the way, the "cost analysis" isn't strictly about the financial cost, but the cost to the computer system as a whole and the ramifications upon the public. It is a completely different and much more serious approach compared with most of the other discussions about Vista which have come to light over the past few months.It is quite lengthy, requiring close to an hour to digest and includes a lot of techno babble, but an interesting read none the less; especially pay attention to the footnotes near the end.

Well fiddle dee dee....it might have made more sense and been more helpful if I had included a link for the address! http://www.cs.auckland.ac.nz/~pgut001/pubs/vista_cost.html#a
