Further development of Windows RT has been abandoned on the Surface RT/2 devices, which means that many devices are lingering away unused in drawers around the world, waiting for new life.
The hardware in the Surface RT/2 is still quite acceptable to be used as a tablet even many years after they were abandoned by Microsoft. For those interested in Windows RT on the Surface RT/2 a newer Windows 10 build can be installed. Instructions for updating a Surface RT/2 to Windows 10* or RT 8.0/8.1 can be found here - https://jwa4.gitbook.io/windows/tools/windows-media-builder
*NOTE! No this will not install a full x86 build!
