|Is this dashboard more pig than horse?|
220.127.116.118 and in this version it is not possible to delete dashboards but I have managed to in earlier versions.
My friend Jerry Weinstock has blogged about this as well.
One particular dashboard that the system is in dire need of for its mobile features is the "Sales Dashboard" as this is the default dashboard for the mobile and tablet clients. This cannot be changed although the default dashboard can be changed within the mobile client by the user after it has been started. See MSDN for more info in this.
In case you do manage to delete it or it has been deleted, Power Objects blog have described how to restore dashboards from instance with this dashboard in it. In short, create an unmanaged solution in that other instance containing the "Sales Dashboard" and then export and import the solution into the instance missing it.
Before closing the window showing the results, open the log of the import and get the guid of the dashboard and then use the url of another dashboard to insert the GUID into the url to get to the "Sales Dashboard" and change it's name and/or the label of the the tab to what it typically is in case it doesn't show up directly.
In case you do not have one, here is a link to an unmanaged solution file (version 8.0) containing just the sales dashboard. SalesDashboard_1_0_0_0_target_CRM_8.0.zip
