RE: My 3 favorite books about boats that I have read more than once are......
When first investigating the Kindle, I downloaded "Kindle for Mac" to my laptop. It is awesome and it's free. It's also available for PCs. Since then, we did buy my wife the newest Kindle, and she won't leave it alone.
As you can imagine, the laptop version isn't as convenient, mostly due to size and glare, but is a nice way to see how you feel about electronic reading. I do intend to buy a Kindle for myself, as it's much nicer on an airplane, or in the airport.
