IDC in a study took apart the tablet and e-reader markets early this year. The tablet market saw an early 28 percent drop in the first quarter of 2011 to 7.2 million units. Just over 65 percent of those were iPads while the rest were dominated by Android's 34 percent and a small amount of Windows tablets. Most of the drop was pinned on Apple being constrained by supply, where iPad 2 backlight issues and a slow production ramp prevented it from delivering more.
