Amazon's Kindle ebook reader has been doing pretty well as a consumer device, but we've always thought it had amazing potential as a textbook reader -- especially coupled iTunes-style with Amazon's online distribution system. Apparently Princeton University (Jeff Bezos's alma mater) agrees with us, because it's just announced plans to publish Kindle version of its textbooks this fall, joining Yale, Oxford, and Berkeley in supporting the device. It's not clear how many books are due to be published on the device or how content like photographs and full-color diagrams will be handled (what's a bio book without red mitochondria? They're the "powerhouse" of the cell!), but we're certain students will gladly make the tradeoff to reduce their backpack loads just a little bit.
