The cold in winter never bothered me as much since I always have gloves on, even in the fall, my hands just get too cold! (Pretty sure my fingers and toes being so susceptible to cold are a result of daily ice skating when I was a kid, and never ever going inside to warm up until my fingers and toes felt like they were literally going to break off if I touched them. So now I get frostbite very quickly.)
But reading out in the sun in the summertime is my problem, it does hurt my fingers to touch the metal. Having my reader always in the Sony cover helps, I can hold it by the cover mostly.
But the best cure has been applying a skin to the reader. While it will still feel warm, it's nothing like it was before and never feels uncomfortable to touch. It helped the cold as well, I could feel it sometimes even through gloves, but no more.
