It's lightweight -- its memory footprint is only the pointer. It uses reset() instead of release(). It's just the same as a simple array, but it will always be deleted.
The extra features of std::vector (appending, inserting, removing elements; iterators; size; etc.) make it nothing like scoped_array.
