Do you think textbooks are obsolete?

In their place would come a variety of digital-learning technologies, like e-readers and multimedia Web sites. I see new schools making this switch.  My daughters currently head out the door with backpacks loaded heavy and I have found myself paying excess baggage fees to accomodate ambitious travel reading plans. As much as I cherish books,  I am tempted by the e-reader.  Let us know your thoughts about this op-ed!
