The device physically, is relatively good for the money.  There are many reviews on YouTube and other places that address that point.  The problem with the B&N system is the fact that you must enter a 'default credit card' to be able to use or purchase any books.

Similarly, if anyone found your child's Nook, they too could purchase anything using your credit card information.
