With Dell’s XPS 10 now off the market, Microsoft remains the sole manufacturer still selling a Windows RT device, according to an article in CITEworld.
Windows RT is a variant of Windows 8 designed to run on power-sipping ARM processors. While devices running Windows RT have longer battery life than those running Windows 8, Windows RT is also more limited. Unlike Windows 8, which is backwards compatible with all Windows programs, Windows RT only runs new-style apps created specifically for the Windows Store, which launched in conjunction with Windows 8.
Microsoft produced its own tablet running Windows RT: Surface RT. Only a few other manufacturers, however, committed to producing Windows RT devices: Dell with its XPS 10, Lenovo with the Yoga 11, and Samsung with the ATIV Smart PC.
The Surface RT was apparently the most popular of the Windows RT devices — and Microsoft still had to take a $900 million write-down on it after it discounted the Surface RT by $150 each due to low sales.
Some pundits have suggested that Microsoft get rid of Windows RT altogether. But Microsoft has said it would continue with the OS and, indeed, earlier this week announced the Surface 2, the successor to the Surface RT. Surface 2 will run on Windows RT 8.1.
Microsoft started releasing Windows RT 8.1 to hardware manufacturers in late August. But the company has not disclosed which manufacturers, if any, have committed to producing devices running on that platform.
