I’ve not had a chance to play with a Kindle, but seen a lot of them in the coffee shops of Seattle (Amazon will soon be moving to a neighborhood very close to mine, in South Lake Union.) My first impression was: cool, but a bit small. Now here comes the Kindle DX with a 9.7″ display and better integrated PDF. Now if Amazon will just offer an easy method for connecting to the arXiv, and I can scrounge up $500 bucks (can I put a Kindle on one of my grants?), I might think of getting one. One question I couldn’t find an answer to was whether one could use the “basic web browser” in the Kindle DX to download PDFs.
