Knowing when to go Metro
You're best off not trying to replace existing desktop apps with Metro apps, except for ones primarily designed for consumption. Don't expect every single app to turn up in a Metro incarnation -- at least not until Windows users are comfortable enough with Metro to attempt working with more sophisticated apps.
