-// IE10 Metro responsive
-// Required for Windows 8 Metro split-screen snapping with IE10
+// IE10 in Windows (Phone) 8
 //
+// Support for responsive views via media queries is kind of borked in IE10, for
+// both Surface/desktop in split view and Windows Phone 8. This particular fix
+// must be accompanied by a snippet of JavaScript to sniff the user agent and
+// apply some condtional CSS to *only* the Surface/desktop Windows 8. Look at
+// our Getting Started page for more information on this bug.

-// IE10 on Windows Phone 8
-// IE10 on WP8 doesn't report CSS pixels, but actual device pixels. In
-// other words, say on a Lumia, you'll get 768px as the device width,
-// meaning users will see the tablet styles and not phone styles.
-//
-// Alternatively you can override this with JS (see source below), but
-// we won't be doing that here given our limited scope.
