Amazon Kindle in the classroom: some results

We often hear about schools that make bold (technological) leaps into the future and much less often about how those leaps went. Recently (last year?), some schools made Amazon's Kindle e-book readers mandatory, and the results are in and they're not that favorable (see this):

Darden is one of a handful of schools that decided to give the larger-screened Kindle DX a trial run in select classes to see how well it fared in the academic environment. And, it's not the first to conclude that the Kindle isn't quite right for its students. Arizona State University recently completed its own pilot program for the Kindle DX and wasn't particularly impressed—the university also settled a lawsuit with the American Council for the Blind, agreeing to use devices that were more accessible to the blind in the future. Princeton was also underwhelmed by its Kindle test; one student described the device as a "poor excuse of an academic tool" in an interview with the Daily Princetonian.

I wonder how the outcome of this experiment will bode for those schools who have "leaped forward" with the iPad"?
