So, yes, I confess: I bought a Kindle 3 nearly two months ago, and it has proved to be as game-changing a device as the iPod. Between the two, the amount of information I can easily carry with me from place to place is staggering.
A wonderful feature that I just discovered is that some publishers enable Kindle users easily to loan their books to one another for fourteen days. This addresses one of the sore spots of ebook users, who have not liked the idea that they cannot pass around their ebooks the way people do with regular books. There is a site that facilitates lending among a very large community of users: www.booklending.com—if you have a Kindle, check it out.
Update 23 May: The lending feature is not nearly as good as I had first thought: apparently, you get to loan the book only once, ever.
