Media in the future of education

As children are spending more and more time watching TV, playing video games, and using the internet, where will reading fall when we become teachers.  Will a switch to media use be necessary in the classroom?  What kind of reading habits will be enforced if students use e-readers for school?  Should the use of this new technology replace books as younger and younger children move to technology?  Would an e-reader keep a child more engaged because of the desired use of media?
