I walk to work every day through the streets of Washington, DC reading the news on my phone and weaving past other pedestrians doing the same thing. Nearly all of us have touchscreen phones, which is great until the temperature drops below freezing and we have to choose between frostbite or Twitter. (You know which option I choose; I've tweeted 16,000 times.)
There is a technological solution to this conundrum and it is called conductive thread. Glove manufacturers can sew this material into the fingertips of gloves, thus allowing you to remain warm while continuing to scroll and pinch.
There are easier solutions -- cut-off gloves, say -- but I think if you're going to use your phone in freezing temperatures, you should go with the nerdiest possible product. These North Face ETIP gloves certainly fit that bill and at $40, they are a big enough gift that few people are going to purchase them for themselves.
