The company paid Google $3 billion for Motorola when its mobile business was still soaring, but a lot has changed in three years. Nevertheless, it doesn't plan on selling it off like analysts want, despite the drag on PC sales, which rose mildly by 2 percent. Rather, CEO Yang Yuanqing said the company is rebuilding its team under new chief Gina Qiao, and hopes to break even within a year or so. "Mobile should be our core business as well [as PCs]," he told Reuters.

Luckily, PCs are still selling well, particularly to businesses, so sales were a relatively flat $12.2 billion and Lenovo still made a profit. However, it needs to execute better on models like the Phab 2, which could have made a splash as the first Google Tango phone but was sunk by lousy components and iffy software. If it keeps doing what it did with the Moto Z, though, it could start to win back fans of the brand.
