I don't buy any book but I would rather download e-books from the internet for free although reading books on computer screen is not a good choice. However, I buy 6-7 magazines about gadgets and mobile phone each year.
I used to buy 20-30 books a year but not anymore.
I still like books, but I am giving most of my time to anime, so I don't buy that many books for the past 2-3 years.
