One Laptop Per Child project founder Nicholas Negroponte told those at the Mobilize conference today that tablets needed to be more creativity-driven than the iPad. While not directly critical of Apple's design, the OLPC lead said Apple was primarily making "peripherals for iTunes" that were meant for passive consumption. For devices like the XO-3 tablet, the focus had to be on active learning and creation, which Negroponte didn't see as an iPad strong suit.
