Like many other here, Vista at best looked like an dubious upgrade to me, with all the damn bloatware that it comes with. But with this proposed new EULA it isn't acceptable at all. I had already made the decision to start playing with Ubuntu before this and this kind of crap will make me accelerate my learning schedule.
If Steve Jobs would get his snobbish head out of his own @ss and look, he would see an opportunity here for him to make mass inroads into the x86 OS market if he would open up and sell OSX that would install in non-Apple computers.
And as for the OEM's, they also need to make a change in their offerings too. As it stands now, you really can't choose your OS to something besides M$ crap from the major OEM's for consumer computers. So if you want to get a computer from a major OEM, you will be stuck paying the MS tax as I call it, making you buy their OS with the box. Sounds to me like this would be good material for a class action suit.
One other thing about this incredibly restrictive EULA; how the hell is this supposed to stop piracy. If anything, this will only encourage piracy and go and make thousands of otherwise law-abiding people go the piracy route just so they don't get ****ed by M$ after spending $300+ for this OS.
