+<p>Device implementations are STRONGLY RECOMMENDED to implement adoptable
+storage if the removable storage device port is in a long-term stable location,
+such as within the battery compartment or other protective cover
+<p>Device implementations such as a television, MAY enable adoption through USB
+ports as the device is expected to be static and not mobile. But for other
+device implementations that are mobile in nature, it is STRONGLY RECOMMENDED to
+implement the adoptable storage in a long-term stable location, since accidentally
+disconnecting them can cause data loss/corruption.</p>
