Lenovo Group not only tops the worldwide PC market, ahead of #2 HP and #3 Dell, but it operates competitive phone and server businesses. Through a series of acquisitions, the Hong Kong-based company has assembled a device-driven product lineup that competes in various technology markets around the world. Lenovo has resurrected the Motorola brand in smartphones and unleashed IBM's former low-end server entity into a fast-growing business. Besides ThinkPad-branded commercial PCs, Lenovos turns out tablets, ultrabooks, software, and accessories. Its sales are fairly evenly sourced from the major world markets of China, North America, and Europe.
