Today Forrester published its revised US consumer tablet forecast [1], updating its previous forecast from June 2010. When Apple's iPad first debuted, we saw the device as a game-changer [2] but were too conservative with our forecast [3]. Since then, we've fielded additional consumer surveys and an SMB and enterprise survey, conducted additional supply-side research, and seen more sales numbers from Apple. We've had briefings from many companies that will release new tablets at CES. All of these inputs have led us to revise our US consumer tablet forecast for 2010 upward to 10.3 million units, and we expect sales to more than double in 2011 to 24.1 million units. Of those sales, the lion's share will be iPads, and despite many would-be competitors that will be released at CES, we see Apple commanding the vast majority of the tablet market through 2012.
