I found this link:

I didn't know you could get an adapter for the HP IPAQ that would add a CF slot and a pcmcia slot.

My question is that if you got a CF to USB adapter:

for a USB Hard Drive. As well as a PCMCIA soundcard like the new Audigy one. You could finally have a pocket PC with large amounts of storage and the kicker for me being high quality sound.

The only problem I could foresee would be getting the drivers for the pcmcia soundcard.
