Usually, when a View requires a lot of bindings, or some UI Elements like a Bing Map, it takes a "while" to load (like between half a second and a second).

I don't want a delay between a "tap" action (like tapping an element on a ListBox) and the navigation action (displaying a new page).

I don't mind displaying the page progressively. For example, for a Bing Map, I don't mind displaying a black page with only a title, and a second later, having the Map appear.

What are the best practices ? It could post a sample if i'm not clear enough
