According to IDC, Apple, Samsung, Amazon, ASUS and Acer are the top 5 tablet vendors based on volume market share in the second quarter of 2012.
Tablet shipments for the second quarter of 2012 (2Q12) grew to 25 million units from 18.7 million in the first quarter of 2012.
The quarter-over-quarter increase in tablet shipments was 33.6 percent and year-over-year growth was 66.2 percent, IDC said.
IHS said share by outsourced manufacturing of tablets remain in the low 90 percent range, hitting a high of 91.1 percent by 2015 before settling back down at 90.4 percent in 2016.
Tablet brands use outsourcing for many reasons, including faster time to market; the leveraging of capabilities, especially for firmware development and hardware integration; and asset flexibility that translates into reduced corporate expenditures and lower headcount.
The biggest contract manufacturer of tablets is Apple partner Hon Hai of Taiwan, also known as Foxconn. Hon Hai accounted for 62 percent of tablet shipments last year.
For other tablet brands like Samsung and Motorola that choose in-house production, their share of tablet manufacturing is not expected to exceed the 12.5 percent that the collective in-house space saw in 2011.
