A couple of people above thought that the man was an unpleasant individual. One even thought he was engaged in some sort of scam.
First, the man is entitled to a working computer.
Second, long before things got this bad Gateway should have flat out replaced his machine. Period. You take care of problems like this right away, even if you lose money and even if you think the customer is being a jerk. You offer him a brand new computer and make it an upgrade. If you think the problem is really unsolvable you refund all of his money and send him to one of your competitors. You do not let things like this fester. Gateway is having serious financial problems and they don't need stories like this being published.
Thirdly, the man is entitled to be damned upset at the way he was treated.
Fourth, Gateway needs to publish the fact, if that is their policy, that it's warranties will be in force only for people they deem to be "really nice".
Finally, it is inconceivable that the man is engaged in any sort of scam. He is out an awful lot of money and has had a non-working computer for literally years. What sort of scam is that? That doesn't even make any sense.
