A while ago I posted about the joys of my new Kindle. Absolutely terrific for commuting - don't have to carry piles of books and can download whatever, whenever etc.
What I hadn't realized at the time of purchase was the challenge of reading on a Kindle when not commuting: in particular, when hanging out at home with toddlers. While those of the under 4 y.o. persuasion are usually not overly interested in "grown up" books when mommy tries to read them, a Kindle is a different kettle of fish altogether. It has BUTTONS. You can press them. You can make the screen do silly things. My main tip to others with toddlers and Kindles ... make sure the wireless connection to the Kindle store is turned OFF when the young ones are about.
