Primary issue(s) for me and dedicated devices is A) I want to be able to access all my music from anywhere (I even publish my collection via my server on the web, database style even), at any time. B) I encode my mp3s big so they take up lots of space compared to 128k you see around (VBR that averages ~200-300+). So 1-10gigs jsut doesnt cut it.... think 100G
