Microsoft's Surface RT tablet remains the most popular Windows 8/RT device, but it doesn't dominate the market for the new operating system the way it did last month.
According to AdDuplex, a Windows ad-serving firm, the tablet's share of usage among Window 8/RT devices has experienced a decrease by almost half when compared to last month's statistics. During November, Surface accounted for an 11 percent share of all usage on the platform.
The device's position in the market was determined through the collection of data stemming from 71 active Windows 8/RT apps on the AdDuplex network on December 7. Surface's lead is "not as stunning as it was last month -- down 5% to 6% overall this month," it said.
In terms of vendors, HP is the market leader with 22 percent, followed by Dell and Acer. Microsoft settled for 6th, which is down from No. 2 last month.
