BlackBerry by Research In Motion

Featured on TV shows in 2003 and 2005; spotted in her hand in November 2008; discussed publicly in May 2009

Oprah first named the BlackBerry as one of her "favorite things" in 2003, and she still uses it—for more than just e-mail. She recently said she wrote an entire magazine article about First Lady Michelle Obama for Time magazine using the device. The anecdote, shared with a crowd at New York's Lincoln Center, could be viewed as a ringing endorsement for BlackBerry maker Research In Motion (RIM). In this case, Oprah also 'fessed up to a slip of the finger that resulted in the accidental deletion of an entire article draft.
