AdDuplex, which runs an ad network for Windows and Windows Phone apps, has posted regular updates on the Windows Phone ecosystem for the past several months, based on data they have retrieved from their ad network. However, the last time they offered a similar update on Windows 8/RT devices was in April.
That changed on Sunday when AdDuplex posted up some new numbers, based on data collected from 393 Windows Store apps that ran the company's SDK. The results show that the Surface RT tablet from Microsoft is still the most used single hardware device in the Windows 8/RT system. In fact, the tablet actually gained market share in between April and August. The data shows that 9.5 percent of the apps on the network are running on the Surface RT, compared to 6.2 percent in April.
