Comment(by scribu):

 Firstly, just because you can set empty custom fields, doesn't mean you
 should. When you no longer need a custom field, just delete it. Therefore,
 returning an empty string or array is ok.

 Secondly, like westi said, most of the time you don't have a default
 value.

 If you really need that, just write a wrapper function:

 {{{
 function get_post_meta_with_default($id, $key, $value, $single, $default)
 {
   $data = get_post_meta($id, $key, $value, $single);

   if ( empty($data) )
     return $default;

   return $data;
 }
 }}}
