Although Android tablet almost doubled their market share, the iPad is still the ruling tablet, with quite a margin ahead of Android slates. Android tablets reached a very good 7.3 million sales in this quarter, while the market is ruled by Apple at 17 million units sold in the last quarter.

The info comes from Strategy Analytics, in case you’re wondering. Apple now owns 68.3% of the tablet market, compared to the 62% in the second quarter of 2011 and it has both the iPad 3 and the cheaper iPad 2 to thank for that. Statistics also show that Microsoft lost 3% of its tiny market share in the tablet area. Android’s big sales resulted in them owning 29.3% market share, basically the same as one year ago. Apple’s share of the tablet market is the highest since Q3 2010, so the Cupertino giant is doing very well, outselling Android tablets by 2:1.

Strategy Analytics analyst Neil Mawston says that in spite of big expectations for Amazon, Acer, ASUS and Samsung the Android world hasn’t yet produced an iPad killer. He mentions unoriginal design and limited uptake of cellular models as the primary causes. What do you think is the reason behind Android’s failure to put a bigger dent in Apple’s tablet market share?
