Just picked up an ipod shuffle for gym/track use. I really like it, you can't feel it clipped on a shirt. Definitely a different feeling than running with an iPhone on an arm band like I used to have. Im a little curious as to why it has a 104mb of space (labeled "other" in orange") and why it wont let me use the last ~75 mb of free space to fill with songs. I tried turning off Voiceover and the "other" space was still unavailable. The only reason I can see is the player uses the flash memory to load the software and buffer songs. Is this the reason?
