I would not use "Metro UI" Microsoft stopped using the term due to trademark dispute with a Metro AG. I recall seeing a notice to msdn developers requesting them to stop using the name some time ago.

I have no idea if it was a valid claim, but easier to just avoid the hassle.

I've used the term just to describe the UI in one word to the HN community. I haven't use the term in the app itself or any official description (landing page, App Store, etc.).
