You know, if any company tried to tell me that my warranty was void on something because of dust, and their warranty policy says nothing about dust voiding the warranty, I would sue the F**K out of them. I don't know what law that falls under, but all I know is that it is pointless and stupid, and should be grounds for a lawsuit. I hope that guy does sue Sony. After doing something stupid like that, Sony deserves all the bad publicity they can get!
