This year I've concentrated mostly on ebooks. One exception was House of Leaves, because the physical book is part of the experience. Imagine my surprise on finding out how heavy it was! And I've read physical books for most of my whole life.

Last week I got another hardback in the mail "Where Mathematics Comes From" and it was also incredibly weighty. Seriously, is this normal? I'm considering getting away from e-reading just for the exercise.
