I’ve been looking for a more “natural” way to store URLs from the printed page (one that didn’t involve dragging the paper over to some device hooked up to the computer). Felix Strates sent me a link to the Cross NetPen which stores PaperClick bar codes. You dock the pen later and surf away. Now if someone adds the “press the button when you hear something on the radio you want to remember” technology to the same pen, you’ll have a super multimedia URL tool! I wonder how we can get URLs memorized off of billboards? Special radio signals going into your car?
