In my experience, I thought e-readers were just a fad, but watching folks use them changed my view. Your mileage may vary, but now I'm browsing reviews for one.
Ugh, I'm still totally against them. Nothing beats the actual feel of a real book in your hands, and you never have to worry about a dead battery. Plus, I love loaning my favorites to friends, which you just can't do with a locked digital file.
