And Longhorn is roumored to support that new MS "anti-piracy" feature, that will require a specific chip to come with it too and it will be totally backwards incompatible solution. - drivers/programs wise.
Just in order to make everything save and sound.
And apparently they have Intel/ Nvidia/ AMD supporting them in the initiative.
We shall see when it happens, but I like my PC free of "security/spyware chips" that is for sure.
