Comment on The Kindle

In terms of innovation, the Kindle is great. However. in terms of cost/benefit analysis, it doesn't make sense. For instance, the device is $359. Now, Krugman's new book is $14.97. I could buy almost 24 books for the price of the device alone. Also, since the books are downloads, I cannot re-sell them. Lastly, I want an elaborate library. Must they technologize reading?
