Yeah...I heard they were developing a 256MB SM card, but there's not many devices that would support it. SM is fine for cameras (Olympus and Fuji are users of it), as 128 MB takes plenty of 3+ megapixel pics (like 160 or so), but it can be kind of limiting on MP3 players. What I do on my Nomad is encode everything as a 96 or 112 kbps WMA file. I think it sounds just as good as a 160 or a 192 kpbs MP3 file through the headphones. That way I get twice the music on one disk. If you need more, you should look at an Archos MP3 player (10-20GB of space, plus built in MP3 encoding). They run around $200.
