Just because the computer industry loves to throw contracts of adhesion around doesn't make them legal. This kind of "gotcha" contract is the stuff of scams that hope to take advantage of the customer.
The customer paid money for a laptop, and that carries certain expectations, such as the laptop being safe to use. The customer may have agreed to some conditions, but it will be very hard to argue that there was a "meeting of the minds" with regards to the customer giving permission to disable some of the most important security features.
There's also a reason why every contract has a severability clause. There are certain things you cannot legally do, even if you have a contract saying you can do them. This is pretty close to that border IMO, but such situations really come down to the judge.
I'm also curious as to why individuals cannot simply toss contracts of adhesion back at vendors.
A standard for this, in which a standard reference format links to your terms, on an "included by reference" basis, stating what terms are and are not accepted, might create some interesting courtroom drama.
