Do you leave your TV *plugged in* while you're not watching? That's the level of power draw we're talking about in a sleeping Mini:
> Sleeping Mac Mini: 1 to 3 watts of power measured by third party, 0.5 watt on the spec sheet
> Plugged-in TV: 0.5 to 2 watts of power
It's true -- one could unplug the 100-inch wall-mounted TV set from its power cable whenever Dancing with the Stars ended, or hit the breaker, or use an exposed [power strip/surge's] switch, to not waste *just* that little bit of juice overnight. Do you do that? When you see some new TV tech in the news, do you rise to this same bait over this environmental issue each time? Are you writing screeds against the Toshiba people for the Frame TV's art features? (In that case, man, apparently you really would have a strong STOP-MESSING-WITH-MY-FIRMWARE-OVERNIGHT fodder from what I've seen.)
It goes to the position Apple has somehow attained in the world, and to the ego-jousting state of discourse on the internet I suppose, that a simple design choice for a power button has this kind of 'rise-to-the-troll' effect. Apple's assumptions about sleep mode and always-on devices are ones the industry basically shares. But hey, blame Cupertino for not saving the world in every way with every product, you know? This is a potentially clumsy design choice, and my first reaction was "Okay, so clearly making it much smaller forced them into some odd compromises."
(Modest practical experience: I have an M2 Mac Mini now at my home workstation. It turns off, and on again, without my mashing the power button. It's set to power on every morning at 5:10am, 20 or 50 minutes before I work on a given day. There is a UI for this stuff. I've probably used the physical Power button four times? When moving the system around, mostly?)
