On the plus side, it is very compact and fits great on the iPod. It looks like it is part of the iPod. It's a great idea.On the minus side:1. Finding gaps on the radio dial can be very difficult, especially if you commute a ways and pass through multiple radio markets.2. The iTrip just doesn't put out a very strong signal, which means that your iPod will always sound like a radio station that is fading out. You'll get no stereo separation and lots of static.3. The way you tune the iTrip to a radio station requires that you play the "song" corresponding to the station you want and then hit Pause half-way through it. This is an elegant solution in some ways, but you wouldn't want to do it while driving!
