Bullshit!!!
About the Longhorn stuff:
It sounds like they are trying to copy Macs again, and where they are "original", it's a re-hash of an earlier faliure.
Prime example: The "dock based" interface. How long has the Mac OS been using this interface? Apple pretty much got it right in OS X (Earlier, and more basic iterations in the OS 8 and 9 "control strip").
And about the Palladium stuff:
Microsoft themselves claim that Palladium itself cannot do anything, and that other applications have to be written specifically for Palladium to take advantage of it. Basically, on it's own, it's useless.
