The only e-book I had been familiar with was on my Kindle; I had purchased a couple of inexpensive children's ones for my two year old. They were exactly like regular children's books, which is great, especially for travel purposes - works great for bedtime stories. However, they lacked the interactive piece that has greater potential for interactive learning. When I first saw the price of this one, I had a little bit of sticker shock, but decided to take the plunge...and he loves it. Loves the reading, loves the games, the making choices (reminds me a little of Choose Your Own Adventure books when I was a kid , albeit a much older kid). It's great, and I see potential for him to get even greater enjoyment out of as he develops over the next year or so.
