I don't think anyone here really understands what Microsoft is actually trying to do. Although they seem to have lost their talent in designing the visual aspects of their systems, the biggest consequence (IMHO) will be what's happening behind those cartoonish colors. Your computers will be so determined to obey Microsoft, they will systematically disobey you.
This is what Microsoft calls Palladium, similar to Intel's Trusted Computing. Of course, there's no trust happening anywhere, so the name itself is a lie. For that reason, The Free Software Foundation has dubbed it "Treacherous computing, arguing that users will no longer have any real control over anything they do with their machines. Even something as simple as installing a program will require explicit permission.
Thank goodness for systems like GNU/Linux, ReactOS, and the BSD family.
