I just checked. I have lots of tech documents and books but it's only ~2 GB.
It reminds me of my first "information holding device", a Palm III:

That had 2 MB of RAM. Still, it held all the lyrics/chords of the songs that I played.
Note: The Palm III originally sold for $400, so I guess a Note Air is a better value now!
