It seems that The Guardian has taken design elements from Metro UI after releasing their Windows Phone app and have applied them to their just-released iPad newspaper. Don't mistake this for a mere copy as the app looks superb on the big screen and does Metro proud.

I see this as well as future implementations with other apps on Apple's platform as a positive sign for Windows Phone.When Windows 8 comes along with the upcoming Xbox Dashboard refresh, we should expect to see more adopters for Microsoft's mobile platform with Metro making its way into competitor eco-systems.
