Books are just one of those things that will never be replaced. (yes, even by kindles)
They will always be known as the best pastime, the most popular way to relax and the most universaly suitable gift idea.
Plus when you're done with them you can carve out the pages and hide stuff inside. Seriously, who doesn't love a good book?
And right now there are some awesome book sales going on at Chapters Indigo.
