Best Practices for Mobile Business Intelligence

Good piece in the Tableau blog.    I would like some more whys rather than just best practices.  Still this is a nice start to think about the watch outs.   I am just exploring a BI application on an iPad that works fine for displaying a dashboard, but the key interactive capabilities needed are just not practical for touch.   And adding a keyboard or mouse makes it less than mobile.    If I am mobile I am assuming that I want to be interactive in a detailed way.   Design for that.
