Cool to see this posted. I've always liked, and now miss PDAs.
The picture marked as NX70V is actually an NR70, which you can tell from the rounded camera, and rounded power button. The NX-70V was square.
The NR70 also lacked the compact flash card slot.
I have an NX-70v, and specifically got it for the CF card slot. The slot was only intended to be used with a wifi card that Sony released, but with an OS patch, you could use regular CF cards, which were much cheaper than Memory sticks. So I bought a third party memory stick Wifi card, and used the CF for storage.
