No. 4 Lenovo
Ashton Kutcher did not unveil Lenovo's new Yoga Tablet before the end of the third quarter, but the Lenovo Miix 10 operating on Windows 8 did receive a third-quarter debut. The company, which has extensive tablet offerings in both the Android and Windows arenas, recently attributed its high earnings to a rise in tablet and smartphone shipments. Holding 4.8 percent of the worldwide tablet market share in the third quarter, Lenovo increased from 400,000 to 2.3 million tablets sold in one year, a 420.7 percent increase.
