Online vs. Real Reading

I think that reading online is could be a way that trees could stop being wasted.  I don't read online, but I think that it would be a good idea to start using a Kindle.  I would prefer to read a "real" book than read online, but I am open to reading online.  I think that people will someday do more virtual reading than "real' reading, but for now books are here to stay.  Nick's analogy is a good way ffor me to understand the way of the reading material.
