I'm not going to argue further than this post, as I've got to get on with finals work (LLB).
You said: "My comments on it's legality are debatable and open to conjecture". This is the first time in the thread you have admitted this.
It is clear you have little understanding of law. If you want to talk about "what MS say" then you are welcome to. Just don't frame MS's point of view as the law, which you have been doing. It isn't necessarily. Eg.
eg. "Since when was an EULA legally binding?
Err... since any contract became legally binding?"
eg. (2). "Anyway, the contract is formed on installation when you click 'I agree', not when you buy it."
Debatable and open to conjecture? Not from the sound of things. But it certainly is. And the point you've just made is a very unreasonable assertion.
That's it from me, folks.
