Overall, the worldwide tablet shipments grew to 47.6 million units in Q3 of 2013, which is a 36.7% increase from Q3 of 2012. Apple's iPad is still the leader at 14.1 million units shipped and 29.6% market share, but that marks a big drop year-on-year. In Q3 2012, Apple had virtually the same shipments at 14 million, but that was good enough for 40.2% market share.
The big difference this year is the growth of Android tablets. Samsung more than doubled its tablet shipments from 4.3 million in Q3 last year to 9.7 million in Q3 this year, which was good enough to capture 20.4% of shipments in the quarter. But, that wasn't even the biggest manufacturer growth year-on-year. Lenovo made a huge jump from just 400,000 shipments in Q3 2012 to 2.3 million this past quarter; and Acer jumped from 300,000 to 1.2 million shipments year-on-year.
Apple's share keeps dropping and Android continues to gain steam in the tablet market. We'll have to see, but this may be the last year that Tim Cook will be able to call an "iPad Christmas".
