+    is_mobile_device? # => Returns true or false depending on the device or
+
+    is_tablet_device? # => Returns true if the device is a tablet

+    in_mobile_view? # => Returns true or false depending on current req. format or
+
+    in_tablet_view? # => Returns true if the current req. format is for tablet view
