I'm a history professor; I teach mostly undergrad courses. Some of my motivation in purchaing the EE was the ability go 'paperless.' I wanted students to submit pdfs instead of physical copies. My plan was to read and grade them on the e-reader side.

Technically, it's possible. It works. But it is far from elegant. Landscape mode would help immensely. Writing comments on the 'regular sized' format of a pdf means that commetns end up HUGE relative to the typed text. The obvious solution is to zoom in before writing comments. Thus, my chicken scratch is smaller relative to the text. But once I save that file, all of the margins are gone; the paper that the student gets back looks as of they typed right to the edge of the page.

Also if I FAIL to zoom in before writing my first comments, I'm stuck.. Once the first comment has been entered, you can't resize. (Well, you can, but if you switch back into commenting mode, the e-reader automatically goes back to whatever size you began in...)

As I said, it all technically works, it's just not smooth.

For the time being, I'm back with the laptop, typing comments into Acrobat Pro. I still WANT to be able to use my EE, but I'm not optimistic that it will ever live up to my expectations.
