First Apple built personal computers, then portable media players, and now the company is manufacturing cell phones. Apple also has its own branded set-top box -- Apple TV -- and its iTunes store is one of the biggest e-commerce marketplaces for music and videos in the world.
What"s next for Apple? What product categories might the company in Cupertino leap into? Car navigation? Video games? Or perhaps something a little closer to home, like an e-book reader or a tablet?
