The Macintosh laptop section of this Best Buy store has a 15-inch Powerbook (left), a 12-inch Powerbook, and a 12-inch iBook. To the left are copies of .Mac and Apple Care, and brochures on the three models.Unlike Apple retail stores, the laptops are clamped down with heavy-duty brackets, preventing you from getting a sense of a computer's weight or heft. You also cannot close the laptop because of the security bracket.
