For products like the Mac Mini, which don’t have a battery, does this mean that a loss of mains power will cause data loss? Because brownouts do happen occasionally…

Yes. I've tested yanking the power and can easily see 5 seconds of data loss for data that was fsync()ed (but not full synced). I'm not sure yet if corruption due to reordering is also possible, but it seems likely.
