Princeton University is one of a few schools in a pilot program with Amazon using the Kindle DX in the classroom in lieu of textbooks.  The early results are mixed, but the one item that was eye-catching: Use of the Kindle reduced paper by 50%.

The strengths of the Kindle DX include long battery life, wireless access anywhere, large screen, and searchable content.  The Princeton students mentioned that some of the negatives were file navigation, organizational structure for document, and PDF file annotation.

This pilot in a university is key to seeing how eReaders can fare in the academic world.  The hope is that this can trickle down to high schools, and perhaps one day, elementary schools.
