"And what is the use of a book, thought Alice, without pictures or conversations?" -- Lewis Carroll

Some days I agree with Alice.  I love books with pictures and visuals.  I love graphs and tables.  I love little illustrations here and there.  One of my favorites as of late has been Dawn of the Dreadfuls which had great line drawings of zombies and mid-action shots.  They were a great surprise.  Plus the cover is all kinds of awesome.  I also just checked out Freakanomics, the illustrated edition, from the library.  I loved the book before, but so much more with the inclusion of graphs, charts, and cartoons.  It really added to the experience.  As a bonus, it kept me focused on the page.  I didn't wander away at all, instead really focusing on the text because I was drawn in by the visuals.

So, Alice it's okay.  You can expect pictures and conversations from books.  They make the written word that much more enjoyable.
