I was thinking of purchasing an usb stick to put my music on, separate from movies which I keep on a hard drive, but came to think that it would not be much more expensive to buy a used iPod touch for that price. There are programs that let you use the media partition as storage I understand. So can I play the files directly with iTunes if I do this, and would it be the same as if I synced them? I also want to be able to use Airplay if I do this. What are the chances of the iPod screwing up and all my files are lost? I would of course move the files temporarily to the computer if I did something like upgrade iOS. Or is it better to just sync through iTunes, and then get the files back to the computer with these programs?
