ebooks

I'm a fan of ebooks because they enable me to have and to carry with me a whole library of books that I wouldn't otherwise be able to afford and wouldn't have the space to store anyway. Another huge advantage ebooks have over hard copies is they're searchable, and you can copy and paste quotes from them. 

But I love hardcopy books as well. I have hundreds and I'm always buying new ones. Sometimes, when I only own the ebook, I feel like I don't really have a copy of the book.
