The TAG is really the ultimate in electronic books. What we loved about the system is that you don’t have to use it. The books cost $14.95 each–so there is nothing wrong with reading the book with your child the old fashion way. On the tech side your child can use the special pen and “read” along as the pen reads the book. This allows your child to have some independent exploration and pleasure of reading a book long before they can truly read it on his own. To us, it’s the best of both worlds-especially since the titles are books you’d want to bring home. Most of the products in this category have been dominated by licensed only books–while there are some in this series as well – there is a commitment here to bring technology and quality books together.
