Yes, I could turn the unit off but it's WAY too easy to get distracted and forget to do that instead of standby. It's not that I'm stupid (many would disagree!), it's just that life is a distracting thing. When I get into work, I am often accosted by clients and /or colleagues before I've even stepped onto the premises, thus requiring hasty removal of CIEMs and fumbling to stop music playback whilst engaged in Q&A. The simple answer to your question is that good intentions would tally with your theory, but real life, for me, often undermines good intentions, and I need a DAP (if it has atrocious battery life) to have the basic ability to power itself down COMPLETELY.
