Well he didn't say anything I disagreed with. If you want my opinion, take a look at this article

>Students at Reed College complained of the slow refresh rate of e-Ink displays, problematic input, inability to load PDFs over the network, and inability to view more than one text at a time as major sticking points. Reed faculty found converting documents to work well on the Kindle to be particularly difficult in most cases.
>Students participating in the test at Darden School of Business, while loving the Kindle for personal reading, overwhelmingly felt the Kindle didn't pass muster in its current state for academic use -- about 4 out of 5 would not recommend a Kindle DX to incoming MBA students.
I came to that exact conclusion after using a kindle DX for a few months. Additionally, battery life & weight don't really bother me. It's lighter than most textbooks, & I don't mind putting it to charge right before I go to sleep. I spend a lot of time looking at LCDs anyway, so that isn't a problem.
