"Historically, Apple has counted approximately 35 percent of its iPad sales in the last calendar quarter of the year," says Jeff Orr, senior practice director of ABI. "Unless Apple can pull off a 32-plus million-unit quarter, sales for CY2014 will be down for the first year since the iPad launched."
