Paper isn't magical but books are, in my experience, a vastly superior medium. A tablet or a pc screen works a while, but it's tiring. Also a book is more portable, more flexible and it feels better to use. I read the most when I'm in bed but I can't stand reading on a tablet in bed. Or in the bathroom.

I spend most of my time at home surfing the internet, browsing forums and writing code. I read all the time online and yet I prefer physical paper for reading.
