Maybe Microsoft should counter it (or pay the OEMs to do it)? Microsoft has the OEMs by the balls,
Actually, judging by Vista's price tag, then I think the ball grasping is pretty mutual. Microsoft needs the OEMs to shift their OS and keep the piracy down, and the OEMs need to ship with an OS that people actually want.
I'm sure they would love to all switch to a free and infinitely configurable desktop OS in the future, instead of promoting someone elses product.
