From the Barnes & Noble website:
Storytime comes to life with enhanced NOOKbooks that invite kids to interact with the text and pictures on the page — allowing them to follow along as their adventures are read aloud to them. With NOOK kids children have a whole new way to immerse themselves in their favorite stories and bond with their beloved characters through the largest selection of eBooks available
.
By the way, a reminder that TeleRead will be at B&N’s press event tomorrow afternoon.
