Worldwide tablet shipments will reach 211.3 million units in 2015, down 8.1 per cent from 2014, according to a new forecast from IDC. The research company said tablet shipments declined for three consecutive quarters in 2015. Despite the challenges facing the overall market, IDC expects two-in-one -- or detachable -- tablets will continue to represent a growing portion of total shipments. With attractive price points, including the introduction of sub-$100 detachables, and platform innovation being driven by competition, IDC said it is confident that the detachables segment will nearly double in size in the next year, recording more than 75 per cent growth compared to 2015. Major platform vendors Apple, Google and Microsoft are all now active in this segment, including the new iPad Pro from Apple. Release
