If making this battery operate that easy, why Natural point didn't make it? I personally don't think weight is a big issue. Consider that your USB cable connecting to the headset will not be light anyway.Hello:
We could have gone with battery power for the TrackClip Pro, but we felt that having the lightest weight device possible was paramount. Also, if we had done gone the battery route, we would have needed a status light to tell you it was "on", then a switch, then replaceable batteries, or a charging system, and then it just got to be more expensive and complex, so a wire it was, and lightweight it is. You can make it battery powered quite easily, just cut the cord or solder something to the clip part, very low power, like 16ma, so a battery could last for 24 hours, I am sure someone will make something, if the market demands it!
My feeling was that Natural Point is making this USB version first,then having the battery version next so it could be sold 2 times. Just like the Japanese toys makers, they make Optimus Prime without trailer first, and then 3 years later they make a version with a trailer.
