I accidentally dropped and broke my car mp3 player, so had to come up with another music solution. I caved and bought an iTrip for my iPod Nano. It sounds pretty good.
What’s good about it is that it allows you to charge your iPod from a standard USB Mini-B. What’s not so good is that it doesn’t have full USB pass-through, so you can’t sync your iPod, and have to stick with that stupid dock cable.
(and don’t get me started on the really annoying connector on my work cell phone …)
