Vista's BS was 90% DRM related. Hollywood and the RIAA had it checking and rechecking the local hardware bus several times sending the same info to the GPU from the CPU, etc. They are so freaking paranoid that every American in the world is pirating their DVDs and MP3s. 90% of it comes from Southeast Asia. Not us.
Stop selling movies to Hong Kong and the like, problem solved! (and stop frakking with us, you dimwitted RIAA toads: Microsoft, Intel! You're better than that!)
EDIT: I miss the good old days when stuff was designed to work, and you used it for whatever you needed, rather than having hardware/software developers "consult" with the RIAA as to how it should work. RIAA doesn't know what the Hades is going on in the world these days anyway, how the Frell should they know how to run MY computer system?
