If it sports an Apple logo, chances are Scott McNulty has used it. He owns more e-readers than one man should and more books than are sensible. Scott lives in Philadelphia with his wife, Marisa. By day he works at The Wharton School of the University of Pennsylvania, and by night he blogs about whatever strikes his fancy at http://blog.blankbaby.com. He has also been known to tweet once or twice under the handle @blankbaby
