   The data point this offers is that "several students" have behaved similarly. Several means 3 or 4.

No, that would sound like 66 out of 70 people preferred the computer version. Also, this answer isn't addressing our bigger concern, which is whether we can generalize from whether students want assignments on paper vs. on computer to whether adults will want books on paper vs. computer. It seems like there could be an important difference that students want to mark up the pages of what they're reading, whereas that's probably a less common urge for people reading books.
