To the original poster - no you are not the only one after this. I bought my N800 assuming it would allow me to access the photos on my Nikon D200 through USB.

I am hoping that OS2008 will support USB OTG and that I can then do this. I am hoping so much that I have already ordered the cable.

Otherwise I'm going to have to mortgage my soul to buy that WiFi adaptor for my D200.

Not sure what else you can do. Someone suggested this device on another thread, but I don't know if it can cope with the two drives that normally appear when you access the N800 by USB.
