Well, that spur-of-moment decision to purchase the Rio S10 player is turning out to be one of the best things I've done lately. After finding out that I can only stuff about about a dozen tunes onto the built-in 64MB memory, I went out and bout a 256MB SanDisk SD memory card, went back onto puretracks.com and brought in my CD collection to pillage songs from and convert them to WMA, and presto! My own portable radio station...all Ryan's hits, all the time :-) I should have done this years ago!
