@Sven Groot: Frankly I think a lot of us developers are going to have a hard time always sticking to the guidelines in building store apps. I know they want everyone to design with a "do more with less" mentality, but there are a lot of apps that cannot be simplified that much. For example, look at what Microsoft had to do with the Messenger app or Mail app. They are so simplistic and crippled, they're almost useless.
