I live in a relatively moderate climate and yes we have some cold days, but I’ve never had cold weather interfere drastically with using a touch screen device. But maybe others have. Here’s a potential solution from Dots Gloves. The gloves have a metal dot on the fingers that supposedly allow you to use your touch screen device without having to chill your fingers. The price looks right at $10 and supposedly the dots won’t scratch your screen. I imagine if these work they will be big sellers.
