This past week, I attended a conference in New York City. As I walked from booth to booth at the Expo Hall, there were contests to enter, tweets to make and lots of checking in on Four Square. As a result, my battery drained more quickly than usual. I would have to stop and find an outlet, sit own and recharge my phone before I could go on. I really could have used an external battery pack!
