So the second version of the Kindle is up for grabs soon at Amazon and looks to have some nice improvements.  If I could get a bunch of books on it without spending too much (especially for anything that I have already), set it up for some good free content, and carry around some technical books and research papers — it’d certainly save some space.

Anyone have the first one (or a Sony Reader)?  I’d enjoy hearing any comments.  Is it easier or harder to read in general?  Does it save space or time?  Any worries about DRM?  Other neat ideas for use aside from commercial books?
