I'm not a fan of Smart Media cards, and I've
read reports that they will be phased out sooner than CF, and as someone already stated here, do not come in as large capacities as CompactFlash(CF).
Fuji/Olympus digital cameras now have models using this new media called "xD" which is the size of a postage stamp, and will (soon?) be available up to 8GB! The reason
their casing is as large as a postage stamp is so we humans can hold and not lose them.
The 32MB or 64MB xD cards are already in the
stores and are competitively priced with
CF and others.
I think synth manufacturers should seriously
consider this new format. When the prices for a 8GB xD fall low enough, xD could even replace videotape in camcorders. Mindblowing!
