Sorry it's taken so long to respond - I forgot to subscribe to this thread. A roadstor is a device that allows you to insert a flash card (or other digital camera media) and it reads your card and burns it to a cd at the push of a button. I think it's fairly new. I read about it in a digital camera magazine.
You can also use it to show your pictures on a tv, as a dvd player, or mp3 player. It's a pretty cool deal!
I just received it in the mail and haven't used it yet, but I'll let you know how it turns out.
