I saw one of these at Best Buy today and was amazed at the tiny size of this bad boy.  Its reasonably priced at $69 and caries 4GB, this image makes me laugh because the image is like 2 times the size of the actual product.  It comes with a nice little sleeve to carry around in with a clip to put it on your key chain.  I like the SanDisk that I posted before and that I currently have but I thought this one was worth noting.

This would make a good gift idea for those of us who have to keep their Audi for another few years until they graduate.  This little guy plugs into the CD changer adapter in the trunk of the car and gives you 2 (left & right) RCA jacks to plugin anything you want.  So from there you can get a stereo to headphone adapter and plug it directly into your headphone jack and now you are directly connected to your stereo without any tape adapters or bad FM modulators.  This would be a nice feature to add to my car…now I just need a spare $65 laying around.  Crutchfield has it as they typically have anything for your car stereo.
