I know zend framework uses a bunch of it.  Zend_Registry, for  
example, extends from ArrayObject.  The DirectoryIterator seems kinda  
convenient.  I haven't gotten that into it yet though.

I think there are more built-in php functions that your objects can  
take advantage of... found this in the unit test code, for example:
<?php

$ar = array(0=>0, 1=>1);
$ar = new ArrayObject($ar);

var_dump($ar);

$ar[2] = 2;
var_dump($ar[2]);
var_dump($ar["3"] = 3);

var_dump(array_merge((array)$ar, array(4=>4, 5=>5)));
?>

On a side note, the initial reaction of a of mine friend to the zend  
framework was that it felt too much like java.  He's a former java  
developer, who switched to php, and now works in ruby as well).
