If you are like me and you have an mp3 player other than an apple you know the feeling of feeling like a second class citizen when it comes to connecting your device to accessories which only support an iPod.
My car, for example, has an an iPod connector into the factory stereo head unit. So, that meant I could only ever use my iPod or iPhone to listen to my podcasts on my 1.5 hour commute into Chicago every day.
Then I discovered this little number and it worked great. It allows you to plug any mp3 player into an iPod dock. Very cool little device.
