Apple's focus might be on its high-end 16-inch MacBook Pro at the moment, but marketing chief Phil Schiller has also chipped in on the lower end of the market -- namely, how he thinks it might affect students. The executive told CNET in an interview that students using Chromebooks are "not going to succeed" in schools due to the systems' limited abilities. The laptops are "cheap testing tools for required testing" that don't properly inspire students, Schiller said. To no one's surprise, he believed the iPad was the "ultimate tool" for K-12 students due to its ability to keep children engaged as well as tools like Swift Playgrounds. "You need to have these cutting-edge tools to help kids really achieve their best results," the exec said.
