I don't have one myself, but I got to examine/hold one when my boss bought it. They're great--you can read books and periodicals on them, and yes, you can put fanfic on them with a bit of technical finagling, from what I've read about them.
The only reason I haven't got one yet is that the cost is so prohibitive--if I'm going to pay $400 for a Kindle, plus $10 for each book I buy to put on it, I want to at least get credit for 15 free books from the get-go.
Although, I suppose I could just get a lot of older books from Project Gutenberg and do the finagling necessary to put them on the Kindle, but I'd still have to buy any newer books I wanted to put on there.
Ah well. I remember reading somewhere that they've come out with the Kindle II, which (hopefully) means that the cost of the original will be coming down soon.
