Topping tech headlines over the weekend, the NPD Group revealed that Chromebook sales earned 21 percent of all 2013 notebook sales.

The Google-based machines hit a total 1.76 million units sold between January and November — quite a jump from the 400,000 units that left shelves in 2012. Online retail giant Amazon also confirmed good news for the Chrome OS system, reporting that Chromebooks took two of the top three “holiday best sellers” spots. Microsoft, meanwhile, took a hit; NPD revealed no growth in Windows notebook sales over the last year. Check out PCMag Live video below, where Dan Costa and Sascha Segan discuss NPD’s claims.

Meanwhile, online shopping grew 16.5 percent during the holiday season, thanks in great part to smartphone browsing and iOS sales. Mobile traffic reached its highest-ever peak during the holiday season, accounting for 48 percent of all online traffic. A large part of that browsing was conducted via smartphones, which drove 28.5 percent of all online traffic, while shoppers used tablets for 18.1 percent of their shopping.

In other news, music subscription service Rdio’s video-streaming venture Vdio made it to the six-month mark before closing its doors. Friday reports touted emails alerting users to the change, saying that “we [Rdio] were not able to deliver the differentiated customer experience we had hoped for.” As reimbursement for unexpired content, the company will hand out Amazon gift cards, according to the email.
