IDC tipped tablet shipments, including 2-in-1 devices, to decline 8 per cent in 2015, representing a notable increase from the research company's previous forecast of a 3.8 per cent drop. Shipments are now expected to reach 212 million with the vast majority being pure slate tablets. The overall trajectory of the tablet market has not changed significantly over the past year and a half, but the 2-in-1 segment -- also referred to as detachables -- is starting to gain traction. While the 2-in-1 form factor is not new, OEMs are getting more serious about this market and as a result IDC expects the 2-in-1 segment to grow 86.5 per cent year over year in 2015 with 14.7 million units shipped. Although this volume is far below that of the more affordable slate tablet segment, IDC believes these devices appeal to an audience seeking an alternative to pure tablets with smaller screens. Report
