Finally got the above-mentioned cf to sd/sm/ms/mmc adapter. I tried it with an sd card, and it showed up as a cf card in the taskbar. I could read it just fine, so I asume that if you put a memory stick in, it would show up as a cf device. BUT, I don't have a memory stick to try that out. Also, my Z is an SL5600. But for me this is great, because I use my sd slot for permanent storage of programs, so I don't want to eject it to look at pictures from the sd card in my camera. For $17.00 it isn't too bad of a risk trying it.
