Laptops with Microsoft’s Windows 10 will be in a heavyweight bout with Chromebooks for market dominance later this year, but no matter who wins, PC shipments will benefit from the clash.

Worldwide PC shipments are expected to decline by a lower-than-expected rate of 3.3 percent this year, and fall by just 1.8 percent in 2016, as Windows 10 and Chromebooks help stop years of bleeding in the PC market, IDC said on Monday. Shipments declined by 4.7 percent last year when compared to 2013.

Rival firm Gartner disagreed, saying that PC shipments actually rose 1 percent in the fourth quarter of 2014 to 83.7 million units. Its report excludes Chromebooks.

The release of Windows 10 could appeal to businesses that want to upgrade PCs but passed on the maligned Windows 8, said Jay Chou, senior research analyst at IDC.

Windows 10 addresses many of the complaints aimed at Windows 8, and its preview version has received positive reviews, Chou said.

The OS could do well in the U.S. market, but it’s hard to project if consumers will immediately upgrade PCs, Chou said.

A lot depends on whether Microsoft offers the OS as a free upgrade or charges for the OS. If Windows 10 is free, people may choose not to upgrade hardware, Chou said.

A welcoming environment for Windows 10

Lenovo and Dell have already issued ringing endorsements for Windows 10, saying customers are anxious to upgrade to the new OS especially after the controversial Windows 8. One of the appeals is the return of the Start menu, and a stronger focus on the desktop.

“Microsoft has the home court advantage, with the installed base,” Chou said. “If Microsoft can help PCs be price competitive, then there is this home-court advantage to maintain Windows share.”

But Windows 10 faces a challenge from Chromebooks, which are low-cost laptops with Google’s Chrome OS. Chromebooks are gaining strength, and helped PC shipments during the fourth quarter last year. Chromebooks were popular with students and consumers during the holiday shopping season, and will increase their appeal as more people move to Web-based computing.

Worldwide PC shipments totaled 80.8 million units during the fourth quarter, declining by just 2.1 percent compared to the same quarter last year. Of all PCs, laptops accounted for roughly 50 to 55 percent of all shipments, of which 4 to 6 percent were Chromebooks.

Many Chromebooks cost under $250 and are packed with features, which makes them attractive, Chou said.

“A lot of times the build quality is better than the netbooks we saw years ago,” Chou said.

Chromebooks vs. cheapbooks

Microsoft is trying to battle Chrome OS through a series of low-cost laptops and desktops that run on Windows 8 with Bing, which is licensed at no cost to PC makers. The low-cost laptops have minimal storage and are mostly for people who don’t need heavy computing resources, and mostly use them to surf the web, do social media and store files online. HP sells Windows-based Stream laptops and an all-in-one starting at under US$200.

It remains to be seen how Microsoft adapts Windows 10 to battle Chrome OS. Microsoft is expected to share more details about Windows 10 at a January 21 event on its Redmond, Washington, campus.

But no doubt, a strong end to 2014 has set the tone for a better PC market this year. Lenovo was the world’s top PC vendor during the fourth quarter last year, shipping 16.05 million units, up by 4.9 percent compared to the same quarter in 2013. HP came close to regaining the top spot it previously held, shipping 15.88 million units and growing by 15.1 percent. In third place was Dell, shipping 10.88 million units, an 8.5 percent increase. A rebounding Acer grew its shipments by 3.2 percent to reach 6.22 million units. Apple was the world’s fifth largest PC vendor during the quarter, shipping 5.75 million units, up by 18.9 percent. Asustek was bumped out of the top five list during the quarter.
