Good luck implementing a USB host controller on the PIC side to talk to
the USB memory device. This is the biggest problem with USB (as I see
it) -- it's a host/client interface and almost totally PC-centric,
since they have about the only Host controllers available (yes, I know
about USB on-the-go, but not every device will work with it and it's
still not simple).

I think using a standard flash card as a removeable transfer medium for
PIC->PC (or another PIC for that matter) is still the easiest and most
cost effective way to do it.
