When I read through the initial blurbs on the new Mini and saw the photos of the power button placement, I was pleased with the change. This removes the risk of paperwork/accessories bumping into it. It also makes a button with almost zero use invisible (I hardly ever turn my computers off—restarting maybe once every couple of weeks). It’s only real function today is turning the thing back on after a power outage (once every quarter if that in my area—UPS for time to shut down as the outages tend to be long when they happen) or the very rare hard reset someone else mentioned. Putting the thing near the fan may impact dust intrusion, but whether in a positive or negative way, I couldn’t say. Your article actually confirms my positive impression of the button placement.
