I am, in fact, a mobile technology power-user, especially when it comes to press events and conventions. My iPhone 4 acts as my notepad, camera, video camera, audio recorder, phone, and full mobile web interface. Without it, I would be lost. As such a heavy power-user, though, I find that my battery life takes a massive hit. That’s where a device like ZAGG‘s ZAGGsparq 2.0 comes in handy.
