Well, there is no mention of it being a tool to launch apps.. I don't believe that's what it's intended for. It's just mentioned as being a library to easily build windows apps in and I think that is pretty cool. If it turns out to be fairly easy to use text/windows/etc.. (like Visual Basic in a way, where stuff like a textbox is handled for you), it would be very useful if you apps could use the features. (Say a text reader for example...)
And remember, it's skinnable, just make a thin skin!
