I'm right there with you. I have an older 256meg mp3 player that shows up as a regular drive... I can drop anything onto it regardless of format, and if it's not a compatible music file it just won't play it. Aside from the capacity it's awesome.
I also have a 1gb video Samsung thing someone gave me... it uses a godawful unstable Itunes style client to do "library syncs" that is slow, bulky, the UI was designed by dyslexic concussion victims, and it chokes on half the mp3 files I put on, even ones I've ripped myself.
Guess which one I use more...
