I had the same thinking, but then I actually did the calculation. As much as I would like it to be the case, the added cost for an Apple computer won't be balanced out by power consumption, even at one dollar per kwh under heavy use. There is an environmental angle, and of course a few hundred bucks a year is a nice saving if you're buying an Apple anyway, but don't try to make it the primary argument for the added purchase cost.At some point, cheap power is going to become a lot less cheap and PCMR gaming PCs are going to cost more to run than it’s worth for the average consumer. Those who have started prioritizing performance per watt will be rewarded and those that thumb their nose at it will be in for a rude awakening. Being able to recharge my M1 MacBook Pro from a battery I charged up using a 100w solar panel gets really enticing really fast when intermittent rolling black outs and higher energy costs start kicking in. Even where I live in BFE we have an issue with someone attacking substations and knocking out power. This is going to get worse, not better. Prepare now.
My main gripe about Apple Silicon is that I (stupidly) underestimated how much markup Apple is willing to add to a product. I'm positive that the cost per unit for Apple using Apple Silicon is much lower than using Intel, and I was dreaming that they would use that to make their platform more accessible. With "everything" integreated in the chip, the manufacturing cost is very low. Instead (which everyone but me saw coming) they use their chip advantage as a selling point to charge more. I wonder if anyone would still be buying Windows if Apple created a 500 dollar laptop and a 200 dollar Apple TV sized "Mac Nano". But the current strategy probably makes them more money, so I don't blame them.
