Last night (the day after Christmas) around 6:50 pm, the entire island of Oahu was without power for over 13 hours. And I found the Storm came in very handy as a flashlight while walking around in Waikiki. I also took photos and a video of the scene outside.
While walking around in the dark, I was also doing some twittering. My battery died a few hours later since I didn't get to fully charge it.
