Excellent point, Tribble. I think there'd be a lot of interest among academia (universities, etc.), for instance.
There are now services for professors to have students submit their papers electronically, and the service runs a check for plagiarism. But right now, the profs have to print those papers out to actually grade them. What if they could load them on an iLiad-like device, read, grade, and shoot the results back to the student all electronically?
My wife’s getting her PhD in English Lit. (has already done a fair amount of teaching) and she’s quite interested in such a device, and thinks the other profs she knows would be too. But it would really have to have an A5 screen to be truly useful for this –- most “everyday” dox are just A5.
