An odd change of focus in the article...
I get that this is about web technologies being used outside of the web browser. (And that's not new - on Windows, embedding IE into an app to cheekily render content has been going on for at least a decade. Hell, I've seen installers that did it, let alone the actual programs.)
But I find it odd that Apple are being lauded for finally improving their lamentable embedded browser, and there's no mention of Google unbundling their WebView component from the OS in Android 5 (Lollipop).
http://developer.android.com/about/versions/lollipop.html - scroll down to "Chromium Webview".
It seems to me that's much more relevant than Google flagging websites as mobile friendly in their search results. In fact, it's pretty much Google doing in Android 5 exactly what Apple did in iOS 8, surely?
