Simple answer: No (I returned mine) (Score 3, Interesting)

From one academic-paper-reading-geek to another: Don't waste your time with the Kindle DX. I am a professor and did order one- with very high hopes of going beyond paper! To warn others, I also posted a review of my experience with the Kindle DX on my blog: http://ecotope.org/blogs/post/Kindle-DX-Not-ready-for-Academic-users.aspx But there was no way to really use the thing the way you need to if you are an academic-paper-reading-geek! I returned it after about a week. Maybe next year there will be a machine with the right stuff! I hope so!
