I think EBook are both related to complementary and competition. Complementary because it is our technology today, we are in the electronic technology and this is the demand of the people. Competition because paper based books has already electronic books for the reason producers want to reach the internet market for their product.
Actually electronic books are better than paper books when it comes to availability and accessibility. But the disadvantage of this is the health hazard. You read your book by screen which causing exposure to radiation especially when you are reading on a CRT monitor. It might also damage your eye sight. Paper based books are better when it comes to a health issue, and it is also environmentally friendly. We do not emit heat and radiation when we are reading. One more thing is, you can read while resting.
