"Using Motorola, just as Lenovo used the IBM ThinkPad brand, to gain quick credibility and access to desirable markets and build critical mass, makes a lot of sense," added Gillett.

Sun Qi, vice-president of industry consultancy Sino-Market Research Ltd, also believes the Motorola unit will extend the Chinese company's performance in global markets.

Lenovo was the second-largest smartphone maker in China last year with more than 40 million shipments, according to Sun.

Lenovo's quick move into portable device markets has given the company an upper hand in future competition, analysts said.

In the past quarter, Lenovo's revenue surged in Europe, the Middle East and the Americas. Sales outside China contributed more than 60 percent in revenue, according to its financial report.

"Lenovo was early to embrace Android as a tablet operating system while the likes of HP (Hewlett-Packard Co) and Dell (Inc) waited for Windows 8 and prioritized margins over volume," said James Wang, an analyst at Canalys.

"Lenovo's strategy has paid off, not only in its home market but worldwide. Lenovo still has the potential to grow its global notebook shipments and has emerged as a challenger in the tablet space," added Wang.

The analyst said Lenovo shipped three times as many tablets worldwide in the past quarter as HP and Dell combined.

Lenovo CEO Yang said earlier the company will challenge Samsung Electronics Co and Apple Inc globally, using a bigger product spectrum and more affordable prices.
