Don’t look now, but Lenovo just became an industry bellwether. While reporting strong first quarter results that include a record $8.8 billion in revenue and $170 million in profit, the tech giant revealed that its combined smartphone and tablet sales have overtaken those of its PCs. Yes, you read that correctly — the world’s largest PC vendor is now a mobile-first company, unlike previous title holders such as HP. It’s not hard to explain the shift, however. About 42 percent of Lenovo’s total sales come from its native China, where the company’s predominantly Android-based phones and tablets fare very well. The firm’s Windows PCs and tablets are also performing above industry averages, but CEO Yang Yuanqing makes it clear that Lenovo is quickly becoming a “PC Plus” brand — IdeaPads and ThinkPads are just parts of a larger puzzle.
