e-Book Formats and Devices Infographic

I’ve been researching e-Books for my library and an upcoming talk I’m giving at a conference and I’ve noticed that not all e-book formats are compatible with all devices. As a matter of fact, it seems that most devices have their own set of formats that it reads and these are rarely congruous with other readers. To help sort this all out I’ve taken a crack at creating my first infographic which displays the most popular devices used for reading e-Books and which of the most popular formats they can read. Please let me know if you think I should include anything else!
