I have one of those loaded up with MP3s for my aftermarket car stereo. It has a USB port on the front. The low profile Cruizer Fit barely sticks out.
On the subject of flash drives... I picked up a 32GB Transcend JetFlash 600 a while back on Amazon and it is wicked fast (at least compared to my other shitty USB flash drives). You can copy stuff onto it in minutes that takes hours with normal USB drives.
