Taking the Kindle plunge

Heaven help me. I just ordered an Amazon Kindle, the electronic book device. Given how much I travel, and how much everyone in the family reads, it seems like it would be a really good deal. I have some qualms, though, like the fact that I can't resell (or loan) books once they're bought. However, I routinely spend $15-30 per trip on paperbacks to read, and I love the idea of being able to grab a new book on demand. I'll give it a try. Expect a full review once I've had a chance to play with it some.
