I've been debating Amazon's extended warranty, and it's just about final decision time. My credit card doubles Amazon's original warranty, and I'm wondering if anyone has experience or opinions on the extended warranty. I read the fine print, and the only advantage I can see is the one-time replacement for dropping. They pay postage both ways, but for $65 you can buy a lot of postage. The folks over at the Amazon forum are pretty much against it. Any thoughts?
