ugly confusing but Microsoft has sold more than 40 million licenses so far and eventually, people might get used to the completely overhauled and reimagined Windows OS. Personally, I like the new Windows 8 OS and their devices. So how is the windows 8 / RT based devices faring in the market? AdDuplex, a cross-promotion ad network for windows platform apps, has released a data on windows 8/RT devices and accordingly Microsoft’s Surface tablet is the single most popular Windows 8 RT device, though the other OEMs are catching up fast with the software giant. Windows Surface holds a 6% market share, closely followed by HP with it’s array of three inexpensive devices. With Microsoft yet to roll out Surface Tablet across multi-retail outlets though they are slowly moving in that direction and its non-availability in many Windows centric countries, the other OEMs might soon reduce the gap with the Redmond giant’s first tablet. The Surface’s direct competitor ASUS VivoTab RT has managed only 1% share so far. It would be interesting to see how the chart changes in the coming months.
