Ed Bott: Windows 10 S: Chromebook killer or the second coming of Windows RT?

I say second coming of Windows RT. From what I can tell, Windows 10 S is practically the same as RT. You can only install apps from the Windows Store, you can only use Edge, and you can only use Bing. 

While I could upgrade Windows 10 S to Windows 10 Pro for $50 more and then I can use Chrome and Google Search, that is yet more money I have to spend. 

And the update process for Windows 10 S is still not as smooth or fast as Chrome OS. 

But to me, the real problem is that at the end of the day Windows 10 S looks like cheap computers while Chromebooks are lower cost but strive to provide high quality, good looking machines.
