The USB port on the Nano and the other Arduinos uses a dedicated chip to provide serial-over-USB support, so it's actually communicating over serial. Boards like the Arduino Duemilanove used a FTDI chip, but I think recently they've been pressing a second Atmega chip into service as a serial-to-USB bridge. If you used the Arduino with the calculator's USB, you'd need a USB host or OTG chip of some sort or you'd need to bitbang it, hence the I/O suggestion.
