Pretty much all that has to be said about the Kindle 2 has already been said in other reviews. I know that the Kindle 2 is aimed at the normal book reader and that Amazon tried to push it on the student market but I was wondering if it would enhance the reading quality for me--a researcher.
I spend my time perusing a lot of old books, some in book form and some in ebook format online. With antique books, the kindle helps tremendously. I am afraid to take antique books out of the house but still like to read and share them with other people outside my home. In ebook format, I can share them without worrying about damaging them. I also like the new-found freedom I have to "take" a google book or other internet based ebook away from the computer and read it elsewhere. (I don't like the idea of having to print out public domain ebooks--it just wastes too much paper.) I spend so much time at the computer reading, I am more than happy to be able to take my work with me outside.
Another good thing about it is the privacy. Every once in a while I get a book that I feel funny reading in public--mostly the 3rd grade reading level historical fiction books I like to read to make sure I can make the information I teach kids at living history events relevant to things the kids already know. This also helps in stopping misconceptions that are taught through some of the more inaccurate historical fiction books out there. I am glad that if I'm reading Horatio Hornblower or the Sign of the Beaver at college on the Kindle, I don't have to worry about strange looks or odd questions. This also helps with Civil War book covers that some people may find offensive.
I cannot emphasis how helpful the Kindle is; however, I do have some issues with it. My first concern is that there are no page numbers! Research-wise, how do you tell someone where a certain quote or fact comes from if the closest you can get is a chapter number?
I also think some of the PDFs displayed a tiny bit to small, if there was a zoom function that let you zoom from 100% to 125%, PDFs would display perfectly. If you flip the Kindle on its side, PDFs are readable but then you can only see half the page at a time. An upside is that PDF files still contain their original page numbers.
That's all I have to say about it. It was a really great present. I can't wait to start reading all of those classics I have been meaning to! I am currently reading The Last of the Mohicans, which I started as a paperback, and am finishing the last 1/4 on the Kindle.
