I have a Kindle- the first one, and I love it. I like the K2 more though, but the differences are small enough that I don't think i need to upgrade yet.
The DX is much larger than the K2, and is fine if you want to look at magazines or textbooks with a lot of diagrams, but I don't think it's worth the extra cost if that is not your intended use. The Kindle fits nicely into my handbag, the DX wouldn't unless it were on the larger size.
I belong to the Kindle Owners group here at Shelfari, there is a lot of information there about what actual users have to say about the Kindle, you may want to take a look at what discussions we have had there. I will tell you that almost everyone I know who has one loves it and are pretty passionate about owning one.
This is the group:
