Right now, Google and its army of Chromebooks is winning the hardware game in U.S. schools. Its market share hovers around 60 percent, thanks in large part to its Education software platform and the availability of cheap hardware. That hasn’t stopped the competition from trying to catch up, however. Last year, Microsoft boosted its initiative with cheaper laptops, a student-specific version of Windows, and a push toward Mixed Reality in classrooms. Now, it’s Apple’s turn to crank up the volume on its educational efforts.
