Hey everyone! So I took the plunge today on a new iPad Pro 12.9" 64GB. I love the screen size, the feel of the 2nd gen Apple pencil, the ability to annotate/erase notes easily, and being able to keep it all in one place with the added benefit of hand-written notes to text for quick finding. What I'm wondering is will 64GB be enough internal storage for the needs of downloading all the books necessary and keeping all the annotated pdfs available via internal storage? I'm more than happy to keep utilizing Google Drive, iCloud, Dropbox, etc. but if you were in the position of transitioning the bulk of your computing work to a tablet, would 64GB suffice?
