I think the iPad is just the right device at the right time, bringing a book-sized intuitive interface to millions of households with kids overnight. Within just months of getting an iPad, my child & I began reading nearly 50% of all our kid’s books in the form of iPad apps.
This revolution is also fueled by the unique quality of ‘apps’ themselves. These small, discrete bits of software can be downloaded from anywhere in the world, then deleted and ‘stored’ in the ‘cloud’ for re-downloading anytime, like a library at your fingertips. They even ‘update’ for free most of the time, staying compatible with the latest OS. It also doesn’t hurt that ‘apps’ are hip. And the prices are remarkable, compared to new print picture books, making them extremely accessible (although the price-point of the device itself will likely remain a barrier to true accessibility for some time).
