Windows RT was doomed from the start, with Microsoft offering only the Modern UI with few apps and shockingly little support for apps on the desktop, which had all the apps PC users ever needed. And now it's over.
At least it sure seems that way. With the first two generations of its own-brand PC line, Microsoft offered the RT-based Surface models, which offered lots of battery life at the expense of support for the apps you cared about, and the Surface Pro, which had the apps but couldn't keep pace on power.
With the third version, the Surface Pro has made great strides in performance, usability and battery life. And the Surface is now built around Intel's low-power Atom lineup - which means it's got great battery life and supports all the apps you know and love (and hate) on Windows.
The death knell for Windows RT? I'd say so. Read more HERE.
