Windows RT is a tablet-focused operating system designed to run on mobile devices powered by ARM-based chips. While Windows RT has been developed for use on tablets and similar mobile devices, it isn’t designed for smartphones.
The “RT” in Windows RT stands for runtime, and unlike the other two versions of Windows 8, Windows RT (also called WinRT and Windows on ARM) is an OEM-only edition that won’t be available for purchase in stores. In addition to running on ARM-powered tablets, low-cost notebooks and other mobile devices from a variety of OEMs, Windows RT will also power Microsoft’s own tablet device, the Microsoft Surface Tablet. (not the Surface Pro 3)
Just a week back, Microsoft confirmed that they had stopped manufacturing the Surface 2 which is a Windows RT Tablet and now we have an update that Microsoft’s Windows RT devices will not be manufactured henceforth, confirms the Verge.
Other manufacturers found sluggish sales and lack of attention from buyers however the Nokia Lumia 2520 did show some variation in sales due to its intrinsic worth. Again, it had no good apps, it had an unclear UI and no different features. The Lumia 2520 tablet was the last tablet running Windows RT. Nokia Lumia 2520 tablets are still being sold through Verizon Wireless in the U.S. starting at $499.99 with a two-year commitment, and for $599.99 without a contract. This is also available at the Microsoft Stores but with limited stock.
With the Windows 10 release, Microsoft has plans to unify the digital experience across various devices and consequently gave a death sentence to Windows RT! It is quite clear that Microsoft is planning on something which is proficient and not vague!
