Is probably good now.
When I was in college I had a PDA (Visor Edge) that I took all my handwritten notes on. It allowed for backup to my desktop after class, lightened the load of carrying a dozen notebooks, and I could add spreadsheets and other data along with it. For any overhead slides I brought a digital camera. Why copy manually what can be copied digitally? The other students thought I was cheating, the professors thought it was ingenious.
These days I would probably find it hard to replicate the old Graffiti input since typing on my phone isn't quite the same (bluetooth keyboard?) but it worked for me and I would try to keep that paradigm as closely as I can.
What is mind? No matter. What is matter? Never mind. -- Thomas Hewitt Key, 1799-1875
