Harry Potter author J.K. Rowling gave Apple an unexpected product endorsement during a public appearance at the Lincoln Centre in London earlier this week. According to the report in Publishers Lunch, Rowling talked about her writing habits and proclaimed that "the MacBook Air changed my life." It allows her to write "everywhere, including some very strange places."

It's not a surprising admission, especially to those who own a MacBook Air. At 13.3-inches and under, it's almost as portable as the iPad and has the keyboard of the MacBook Pro. It's the best bring everywhere, work everywhere device that Apple offers.
