Tom Mainelli, research director, Mobile Connected Devices, as quoted in a report from IDC:

The vast majority of consumers continue to favor the iPad over competitors, and Apple is seeing increasingly strong interest in the device from vertical markets—especially education. While iPad shipment totals are beginning to slow a bit in mature markets where the device saw early traction, growth in other regions is clearly more than making up the difference.

IDC reports that the iPad now comprises 68.2% of the tablet market, with Samsung the next closest competitor at 9.6%. The report notes that the companies chasing Apple are making inroads via 7-inch tablets. It is interesting to think how Apple’s 7-to-1 advantage might change if they were to release an iPad mini.
