Pssst, nobody heard this from me, okay?
I was emailed a picture of the prototype PDA geocoin. It looked good in the sample pics that I was shown, but I understand from the minter that the coin was sort of an under-perfomer out of the box. I don't understand all the technical jargon but there was something about a second prototype being made due to short circuits, excessive battery drain, and software problems. Besides that, there may be a need for a total redesign of the casing and circuitry to prevent the aforementioned shortcomings. I also hear there is talk in the redesign of possibly eliminating the stylus and using speech recognition.
But . . . remember . . . you didn't hear it from me
