The Standard for all Windows 8 apps

Is anyone else as impressed as I am with the Great British Chefs app? It truly is a beautiful app that hits Microsoft's Design Principles right on target. In my opinion, this is the standard of what a true Windows 8 app look like and behave. If all Windows 8 apps were to this quality, - and of course if Windows 8 got more of the top name apps, like Spotify, HBO Go, etc. - I think Windows 8 would be in a much better position. Windows 8 apps would definitely stand out from the apps on other operating systems.

What are your thoughts of it and how could other apps reach this standard?
