A wee bit late but if you're still curious:

interior_ptr<T> is useful if you need pointer arithmetic in managed code or a pointer that can reference a managed or native object. It doesn't pin the referenced object and instead gets updated by the CLR when the object moves just like a handle. Can be useful for some functions that can operate on managed and native objects as a native pointer can be passed to an interior_ptr<T> argument.

pin_ptr<T> is useful if you want a managed object that can be referenced by native code. It stops the GC from moving the object so the object's address can be safely assigned to a native pointer as long as the pin_ptr<T> is alive. You see this used a lot when people manually marshal System::String to a char*.

Cheers!
