The new generation of textbooks will be available on the iPad, saving schools the expense of books not to mention saving millions of trees. ZooGue’s (http://www.zoogue.com) new BinderPad offers a way of carrying the tablet of the future in a three-ring binder from the past,” says ZooGue CEO Tim Angel.

The BinderPad weighs in at 3.5 ounces, and is only a half-inch inch thick with the iPad inside. It costs US$29.99 and users can just pop it into any three-ring binder.
