The New York Times has an article about the use of a Kindle while traveling.
"Even so, I’m taking a Kindle with me on this flight, for the first time. Amazon first offered its Kindle, a device for reading e-books, a year ago, and I don’t know why I waited so long to buy one. I can’t seem to put it down. It’s ideal for book reading — lucid, light — but lately it has become something more: a kind of refuge."
