The case for dumping Windows RThttp://bit.ly/1bNsa9t
Before, I felt that there would always be a place for Windows RT in Microsoft's arsenal of operating systems, whether it would end up on smartphones or would eventually replace Windows Embedded. But after using the Dell Venue 8 Pro for the past week and witnessing its combination of processing power and efficiency, I'm convinced that we're going to be seeing more and more x86-based tablets, phablets, and even smartphones in the near future.
There a few of trends working in x86's favor. While ARM processors are currently still more efficient than Intel's Atom processors, handsets are becoming larger and larger and are being equipped with higher capacity batteries. Support for x86 architecture in mobile devices has also extended beyond Windows-powered machines. x86 will be supported by Tizen (whenever those devices eventually come to market), and it's already supported by Android--the Samsung Galaxy Tab 3 (10.1") runs an Atom processor. And, of course, Microsoft is intent on unifying the Windows, Windows Phone, and Xbox platforms. While the low-level differences in Microsoft's platforms could be abstracted away with WinRT, there's little reason not to go one step further and simply go with a single platform.
All of this can only lead to one eventuality--x86 everywhere.
