Microsoft spokesperson says removal is to “stay consistent” with naming structure.

Microsoft Makes Major Announcement In Los Angeles

Microsoft’s ARM-based Surface will no longer be known as the Surface RT after today.

After dropping the RT designator for the newly-launched Surface 2, Microsoft has removed the RT from all of the product pages of the original Surface as well.

The RT in Windows and Surface RT was intended to differentiate the platform from the traditional x86 ecosystem, and the x86-powered Surface Pro. The problem with the RT designator is it doesn’t have a clear and commonly understood definition for the layperson. Microsoft’s official definition for RT is “Run Time”, the name of the toolset that allows developers to cross-develop code for both x86 and ARM platforms.

In an interview earlier this month in Australian tech publication ARN Microsoft Surface product manager Jack Cowett said that Microsoft dropped the RT from the Surface 2 because it had proved confusing for customers.

“We think that there was some confusion in the market last year on the difference between Surface RT and Surface Pro,” he said. “We want to help make it easier for people, and these are two different products designed for two different people.”
