http://www.griffintechnology.com/products/itrip/Griffin Technology has introduced the iTrip, an FM transmitter for Apple's iPod that can play your music through any FM radio. With the device, "you can have the cleanest possible signal, because you can choose any radio station on the dial to tune for the best performance possible. You do this by 'playing' special station codes directly from the iPod itself." According to Griffin, the iTrip does not need batteries, it receives its power from the iPod's headphone jack, and it can rotate out of the way to charge the iPod while still in use. The iTrip is available for pre-order now for US$35 and is expected to ship this spring. If this sells well then maybe this will be a future feature for the iPod, built-in FM.
