Query: Lost my money on a piece of junk

I bought this on the eve of my trip abroad. Poor thing... it refused to turn on after being turned on fewer than five times during my outbound flight. Needless to say I was never able to actually use it during my trip on land, so I basically had an extra piece of plastic in my backpack. When I came back home -- you guessed it -- it was too late to return it. Bottom line: I lost my purchase money, with agony and frustration added for free.
