i'm torn between physical books and kindle versions. they both have their benefits. i have an easier time sitting down for a long time with a physical book, because i'm not as tempted to check my email, but kindles are really nice how you can highlight and unhighlight them and jump from page to page. i think i prefer kindle for how-to books, and physical books for fiction, comics, art, and photography.
i hate audiobooks though. podcasts too. they're soooo slowwwww. i might as well watch 10 movies back to back, or read the book three times.
