You're missing the point.

The value judgement for using a web rendering engine on your _closed_ system barely touches on "cross platform" benefits. The primary concern is whether or not the rendering engine saves you time and effort.

People seem to forget that browser engines are fantastic at a wide variety of tasks:

* Best in class UI layouting.

* A great scripting engine.

* Very performant rendering pipelines (for what they're doing).

* Easy extension points when integrating with your native layer (e.g. exposing your own 'native' JS objects).

* Fantastic dev tools.

* Etc.

Browser engines are a _platform_. Why reinvent the wheel?

XAML is best in class, HTML is legacy and illogical

> A great scripting engine

yet a crappy script language
