Found an awesome theme pack that features a Vista feel.  It's by xcilion who runs XCSkins.  The theme is called Windows Vista Portable Edition.  The skin is supported on both VGA and QVGA devices.  This skinsuite isn't supported or licensed by Microsoft, and xcilion is quick to point that out in the skin information, but he does a great job of getting the feel and look down in my opinion.
