I love gadgets. Always have, probably always will. But few have become as critical to me as LiveScribe Pens.
The technology is pretty cool. It's a pen that creates a digital version of what you write, and as an option can sync an audio recording of what's going on around you while you're writing those notes. It doesn't trascribe your handwriting into text (well, the newest one tries, but you need EXCELLENT handwriting to make use of it). But having your own notes and the audio to go with it is a huge benefit to me both at work and in my gaming.
