Just to offer another way of looking at this:
Based on your post I'm guessing that you bought a system with XP installed and then upgraded it to Vista?
And at some point your biometric authenticator stopped working since it doesn't have a Vista driver?
And you want warranty support out of Dell after your warranty expired but refuse to pay for the extended warranty?
It was pretty cool of Dell, btw, to offer to help you if you buy the extended warranty now instead of saying you should have already had it. Imagine if cars or basically anything else that's not high-tech allowed you to do that.
Anyway, I'm not saying you are wrong or right, just saying that there's more than one way of looking at this. I've been on both sides of this battle and the dumbest statement I've ever heard in my life is "the customer is always right". Tell that to the guy who stuck his laptop in the oven to "unfreeze" it, or the guy who demands that his 10 year old graphics card be upgraded for free to play the latest games, or the guy who dropped his phone in the toilet and demands a new one because it was too small and slipped out of his pocket so it's a design flaw.
