I am actually surprised to see ipod and iphone topping the ebay trends list, as I would never consider buying either on ebay.  You might as well try out a few Nigerian scams as well as bid on a used ipod on ebay.  If you are luck enough to not get a broken or malfunctioning gadget, you still face the impostor items.  Some may describe the search results as a mine field, yet iphone tops the list.  I guess you always have the protection of the ebay feedback system, but really, is there really a huge market for used cell phones?  I would always want to guarantee that I at least have a manufacturers warantee on such a pricey and problem-prone electronic device.
