Griffin, one of the most innovative hardware companies out there, has just released a neat little $40 gadget that takes audio from your computer and broadcasts it to any nearby FM radios. This solves the problem of how to distribute the music from all those CDs you have ripped to your hard drive. It also means you can rebroadcast Internet radio stations to other locations in your house. RocketFM plugs into a USB port, and works with both Windows and Macs--a perfect complement to iTunes.
