What in the world ar you guys doing with your ereaders?
My original K3 was replaced because they had a batch with a known problem where the letters & numbers rubbed off. As the CSR said "That's not supposed to happen." It was replaced free of charge with a refurbished unit. That's the one I've just gifted to my mom since receiving my Paperwhite this Christmas.
My husband's K3 was replaced, because his accidentally slid of the roof of the car. He was juggling too many things, set it too close to the edge and it slid off, breaking the corner and damaging the screen. His replacement, also free of charge, was actually brand new.
