When Microsoft Corp. planned Windows RT operating system, the goal was to create a platform that would feature Windows look and feel and have support low-power ARM-architecture application processors in a bid to enable devices with a day or longer battery life. With the emergence of ultra-low-power Intel Core “Haswell”, Windows RT is no longer needed.

During Lenovo’s press conference at IFA 2013, Australian marketing chief Nick Reynolds said that Intel's latest ultra-low-power Core-i-series 4000Y-family “Haswell” central processing units have eradicated the choice between long battery life and high performance, reports Engadget web-site. At present, it is possible to create Microsoft Windows 8-based devices with all-day battery life, which is why there is no need for ARM-based application processors and Windows RT OS.

Lenovo IdeaPad Yoga 11 based on Nvidia Tegra 3 application processor and Microsoft Windows RT operating system was recently discontinued by the manufacturer. The company continues to sell IdeaPad Yoga 11s, which is based on Intel Core i-series microprocessor and Windows 8 operating system. Lenovo was one of a few adopters of Windows RT in general.

Earlier this year Intel announced new 4th generation Core i-series “Haswell” processors with standard design power of as low as 4.5W, in addition to existing high-performance chips with 6W SDP. These chips, to be available in the second half of 2013, will allow device manufacturers to produce the first fanless 2-in-1 and tablet designs based on the Intel Core “Haswell” processors that are designed with performance in mind.

By introducing chips with 4.5W SDP, Intel in many ways blurred the line between Atom CPUs designed specifically for low-power operation as well as Core microprocessors developed for high-performance applications. Essentially, with new chips Intel also blurred the line between tablets and notebooks when it comes to feature-set and performance. In addition to other after-effects, Intel’s low-power chips also deflates the importance of the already ill-fated Windows RT platform.

Windows RT is a fully-fledged Microsoft operating system compatible with ARM-architecture application processors and incompatible with the vast majority of programs developed for Windows, something that clearly discourages anyone from using it. Given the fact that it carries Windows name, it confuses many buyers as people expect compatibility with their applications. Many PC makers, including Toshiba and Samsung, decided not to offer Windows RT-based devices early in the lifecycle of the OS so to avoid the misunderstandings. Microsoft is currently working hard to improve software support for the Windows RT platform.

Pretty much. Windows RT was a shot at Intel to get their power usage down, and it worked.

However, I've been using our office's SurfaceRT on Win8 the last month and it has totally be usable and still gets 8+ hours out of a single charge.

I agree that windows RT is pretty much redundant, although I suspect its poor popularity is in large part due to the artificial limitations MS built in. It is also worth noting that SDP figures are somewhat misleading.
