last month, Amazon.com sold more e-books than real (paper) books.
surprising.
but I can see some real advantages to them:
1. older people who can't see as well don't need to find large print books (which are barely available). all they have to do is click a button and bingo, the font is as big as they need it to be.
2. you don't need good light to read an e-book - the screen is lit.
3. takes up less space, obviously.
4. no one can lose your page LOL
so in a way, its not hard to see why..
for the same reasons why newspapers and magazine sales are down globally the last 10 years, same with real books.
