Query: A very unreliable piece of electronics

Sure, everybody loves these, myself included. But do your own research ... these are incredibly fragile, flaky devices. My daughter is on her second one in a couple of years. Her first model, a 4GB lime-green model, lasted one year and a half. Two months ago, she bought a 20GB model, and after two months, it is fried, dead, kaput. But talk about Teflon products! Nothing seems to be able to stop the momentum of the iPod.My advice: you better buy the extended warranty. The iPod is warranteed for one year, but, as I understand it, if it breaks after 6 months, you have to pay Apple a $29.95 shipping and handling fee to get it fixed.So, in effect, you've bought an extended service warranty by default it it breaks after 6 months, which seems rather fraudulent to me, since it is supposed to be under warranty for a full year. Very dishonest on Apple's part."Caveat Emptor" ... the words never rang truer.
