No longer are the days when people would photo copy a note or a page of a copy. People now a days say "email it to me" or post it on FB. Thus, the other day, I was taking a commuter train from the burbs to NYC and noticed lots of Kindles instead of reading the WSJ or NYTs. Thus, with the advent of another e-book reader online - B&N EReader - I do wonder how this will make sharing books easier or harder in today's connected society. http://www.wired.com/gadgetlab/2009/10/nook-is-different/
One thing for sure, you just cant tear off a sheet from a book anymore.
