The device had an interesting collection of storage options. 
*4MB (yes MB) of onboard flash.
*A 2 Type II / 1 Type III PCMCIA sot.  PCMCIA cards are physically gigantic by today's standards.  There are adapters to put CF and/or SD cards into PCMCIA slots, so, with the right adapters it could theoretically handle, very slowly, two 512GB SDXC cards.
*Pico/Mini Flash card slot.  Good luck ever finding a card to fit this very short lived and unobtanium standard.  It was about the physical size of a modern SD card.  I understand that it was a bootable media.
*A docking station with a floppy drive in it.
Note that it predates USB existing.  It predates WiFi.  It predates Bluetooth. 
It has a wired modem compatible with the Japanese phone networks of the time WITH voice capabilities to use it as a wired phone answering machine and speakerphone. 
Stereo speakers.
Getting data on/off this thing today is pretty much by physical media or, if you have a docking station, potentially through the RS-232 serial port that only exists when docked.
Back in 1996 I had the opportunity to buy a brand new one for $1400 and passed on it.  That is $2200 or so in today's money.  I see this machine as the spiritual predecessor of the Pandora and now Pyra.  Super compact, clamshell, LOTS of storage options for it's time.
The last time I saw one on Ebay was about 6 years ago.   It went for right at $950.  The floppy dock port replicator sold separately got $450.
