yeah. i tried to get a free one from microsoft a while ago, it didnt work though. they had this page you filled out and they would mail you a free USB flash drive with information about some product. but a couple months after i filled it out, i got an email that they were out of supply. 
Just buy one your self 20$ for 256 megs it’s worth it.
good idea. i want to get a better one. when i got mine, a while ago, that size would be expensive. but now, since theres much bigger ones, the ones like that arent quite as expensive!
My uncle has those a 256 MB one, I currently don’t have any but now that I think of it, I might buy one.
i just dont NEED a bigger one. i could get one… but i barely and rarely use my small one. so why would i go waste my money.
I have a 512MB MP3 player (With a 512MB SD card included) which I’ve used ALL the memory with my music. I also had a 1GB Memory Stick. Don’t know where it is right now though… <_<
