Lacking a new product launch in March to help spur shipments, Apple's iPad saw a lower-than-predicted shipment total of 14.6 million units for the quarter, down from 19.5 million in 1Q13. In years past, Apple has launched a new tablet heading into the second quarter, which resulted in strong quarter-over-quarter growth. Now, Apple is expected to launch new tablet products in the second half of the year, a move that better positions it to compete during the holiday season. Meanwhile, the other two vendors in the top 3 also saw a decline in their unit shipments during the quarter. Second-place Samsung shipped 8.1 million units, down from 8.6 million in the first quarter of 2013, although up significantly from the 2.1 million units shipped in 2Q12. And third-place ASUS shipped a total of 2.0 million units in 2Q13, down from 2.6 million in 1Q13.

Not all vendors experienced a slowdown during the quarter. PC stalwarts Lenovo and Acer both re-entered the top five this quarter. Lenovo continued to make headway into the world of mobility and for the first time had shipments surpass the million unit mark in a quarter, shipping a total of 1.5 million devices. This was up 313.9% from a year ago and enough to capture 3.3% market share. Rounding out the top 5 was Acer, which shipped 1.4 million tablets in 2Q13 for 247.9% year-over-year growth and an increase of 35.4% over the first quarter of 2013.
