HardwareLust: I carry a lot of devices on me. Just going into work, there’s the iPhone, the Blackberry and the Kindle Touch. Sometimes a camera will come with me, or the iPad. This means I go through a lot of battery power. I carry a PowerBag that’s got a built-in recharging litheon ion battery for this very reason, but when I go out to the bars on a Friday or Saturday night, I need something a little more portable.
