Arve said that the power state was equivalent in idle and suspend, but
that they preferred suspend because it stopped any periodic timers. I'd
be more interested in making sure that unnecessary timers aren't running
than focusing on automatically entering system-wide suspend - Nokia have
been managing this since 2005 with good results.
