Answer 1

Apart from retained there are also other modifiers that on occasions may become quite useful, e.g. 'copy' when assigning blocks to class member variables, or 'readonly' which ensures the property can't be written to. Also don't forget about 'dynamic' properties when working with Core Data, and the possibility to execute custom code when assigning or retrieving a property (when defining custom getters/setters instead of using @synthesize).
