When I initially ordered my N900 from Amazon I ordered the offered 3 year warranty. This warranty is from a company called Square Trade. I hadn't yet done anything about that warranty, but since I canceled my order with Amazon and went to Dell instead I decided to go in and see how it works. I tried creating an account through their web page, but I never received an email. So I called them. The guy on the phone was very helpful. He created my account for me with a temporary password. I then explained to him that the warranty was purchased back in October and that I was wondering if the 3 year warranty started counting from the time of purchase or from the time of the product delivery. He said that it starts from the time you purchase the warranty. Oops #1. I then explained to him that I had canceled my device order through Amazon and that I was purchasing it from Dell instead. I asked him if the warranty would apply to the device purchased from Dell and he said that it would not. He said that they can transfer a warranty from person to person, but not from device to device. Oops #2. The good thing is that the warranty can be canceled within 90 days of purchase for a full refund. He was helpful enough to cancel it for me. I still think I am going to purchase this warranty for the device, but I am going to wait until it ships.
