Barnes and Noble is not a very useful place to buy anything.
On numerous occasions I have gone there looking for a book. They promise to order it, I return and not only is the book not there, but there is no record that anyone ordered anything for me. As soon as I discovered that I could get the book used in good condition from Amazon for a fraction of the price, I quit going to Barnes and Noble and other mall bookstores.
Apple's stuff is hugely overpriced, but it is well designed, and they do have it available to try out in their stores, which are among the most inviting ones in the mall.
