Lenovo may not be considered tech royalty, but it's definitely blue-blooded. The company was already the largest PC maker in the world's most populous country when it acquired IBM's PC operations for approximately $1.75 billion. Six years later, in 2011, it toppled Dell as the world's #2 PC company. Besides desktop and notebook PCs (nearly 95% of sales), its products include smartphones and tablets, workstations, servers, storage drives, and IT services. It also offers IT management software under the ThinkVantage name. Lenovo's main facilities are in Beijing; Singapore; and Morrisville, North Carolina. It has research centers in China, Japan, and the US. Lenovo generates nearly half of its revenues in China.
