I've seen Isotoner gloves that have the little nubs on the end but I have to imagine those only work with reactive screen. iPhones are captive screens which use the electrical power from your finger.
Those iPhone gloves must have some sort of conductive material in them. Interesting!
I don't know what the android phone use for screen reactive or captive. I like captive better. People like me who have tree trunks for finger can use just about anything on the screen!

I wish I could find a 2TB external hard drive in my stocking. Alas, no stocking, no luck and not a chance! Did I mention I really hate xmas?!
