THE RACE IS ON: The Wall Street Journal recently reported that Chromebooks now account for 19% of K-12 market for mobile computers in 2013, according to data from Futuresource. (Google's VP of Product Management first shared these numbers back in October 2013.) It's a big leap for Google, whose Chromebooks were in less than 1% of the market a year earlier. Apple's iPad is still in the lead with an estimated 43% of market share. The biggest loser? Windows--which saw its market share slide from 47.5% in 2012 to 28% in 2013.
