I've been pretty lucky in this subject. I think I only ever had one stuck pixel and it was on a DS Lite that I replaced. Unfortunately both of my Lites suferred scratches due to Ouendan use (I didn't know about screen protectors until it was too late.) I kind of want to purchase a new one so I can ammend that, but I don't want to have to pay a pretty penny on eBay or whatever.
Dr Pepper. It's an intellectual drink, for the chosen ones.
