Wow, that is an interesting photo. I'd love to see a higher-res version -- I love knowing how things work and how things fail is fascinating, too.
There are two different warranties; I was alarmed to be told that my new Kindle wasn't eligible, but I then noticed that the linked page was for the $40 Wi-Fi only warranty. The $50 warranty for the 3G/Wi-Fi version is here:

I'm seriously considering it. You never know, and peace of mind is nice.
Enjoy Melbourne

I have a friend in the area... I hope to visit someday! (With my Kindle for the long flight, of course!)
