why is the battery atached to the device?
so when I have the time, I will probably disassemble the unit, remove the bat, print a more stream lined housing for the display and a separate dongle housing for the battery. the battery is what makes the unit big and heavy and since its all wired any way, separating the battery housing to a dongle means it could be worn on a necklace or kept in a pocket.
just a thought. not a serious complaint or suggestion : P
