Broad generalities leading to an advertisement for Starry Night software resulted in my disappointment. This book provides so little content that there is really no point in buying it.

I confess to a severe case of bias: I work at Simulation Curriculum, publisher of this book. So of course take everything I say with a grain of salt, right? That said, I'm really proud of this book. I think it is filled with excellent content, is well written and makes really good use of this wonderful new interactive book platform. I'm very curious about whether readers of enhanced iBooks will care that it's 240 meg. It feels like kind of a lot for a book, but that's mostly because of the many multimedia elements, which I do think add a lot of value. Anyway, here we go. I hope you enjoy reading "Backyard Astronomy" as much as we enjoyed making it. - sm
