And if you file it under your homeowners, or even a seperate policy just for your computer, when you go to cash in on the insurance policy in the even of a claim, that will be a mark against you and could lead to later on raising your rates. With the Dell insurance, your home/auto insurance does not know anything if you drop it and send it back into Dell. Insurance companies are VERY picky, and will mark anything against you they can, including filing claims, even though they say they don't all the time. A friend of mine works for an insurance company, and even if you call in and ask a question about whether something is big enough to claim or not, and you tell them your name, they will file that in your records, even if you decide not to file a claim, and it could potentially be a factor in raising your rates.
So bottom line, get the Dell insurance, not anything related to your home/auto insurance.
