I thought I should add my cents here.
I used my Jetstream all of Fall 2012 semester for class. And I used papyrus for all 12 of my graduate credit hours. Amazing app.
I submitted my final reflections in one course via papyrus thanks to its syncing function with dropbox. I plan to use it again this semester which just began today for me. This app is one reason why this tablet hasn't yet died off for me personally.
Thanks papyrus devs.
Only thing I would like to see is an option to completely disable touch as I end up moving the screen around with my hand (maybe because I'm a lefty?) I feel like I can't fully rest my hand on the screen like I want to because of this. And one other thing which may fix the first problem- I would like to see a paper size option that is exactly the size of the jetstream screen. I like pages that I can look at one at a time- not scroll around on.
