Apple will stay out in front of the tablet market for at least the next four years, Gartner predicted in a long-term estimate on Tuesday. The analyst group saw sales for the entire tablet market for 2012 nearly doubling, up 98 percent to 118.9 million, with Apple still in the clear majority at 73 million. While the gap would close, Apple would keep the largest piece of the market even until 2016.
