$40 is A LOT for a single chip in what is typically a dumb display. It doesn't seem to do much: it doesn't provide added end-user functionality by running TV OS, it doesn't do FSAA on the image or anything unique like that to increase image quality, it doesn't upscale, it basically seems to... run the webcam and allow the attached Mac to do things like control the brightness over the display connector. All of this could have easily been handled with an off the shelf chip that probably costs under $3, so cheaper by a factor of ~13.
It doesn't have a good use
today. If that's the windmill you want to tilt at, we can look at UWB (eventually used to good effect with airtags...which launched to several generations of portable devices pre-seeded in the market with UWB support) or Lidar...which is...well...good for focus and placing IKEA furniture in your living room. Jury is still out on that one. You know Apple is all about Walled Garden Lockin and they get there by doing oddball things like inserting an iphone 8 in their monitors.
I had a Dell Ultrabook with a 2 core i7. It started out having good battery life, but in current WFH COVID times, running Teams and Chrome and McAfee meant the fan was on 100% of the time...I think the venn diagram of available resources, Software needed, and quiet operation just flat didn't overlap anymore. It couldn't sleep reliably. It was light and portable. I think in quantity, they were $650 a piece.
Due to a crazy series of events, where our IT didn't want to support more than two SKUs and I had log analysis needs that slightly outstripped our current base business ultrabook, I ended up with a Precision 7560. I've railed on some of the cognitive dissonance here before. It's a 64 Gb, Xeon processor, discrete Nvidia A3000 GPU science workstation. It has, literally, no supported sleep modes, is always warm, and has that 3.5 hour battery life if you don't do anything to 'spool it up much'...near as I can tell, it's a $5500 MSRP beast. it has a 17" screen and a 10 key keyboard. It weighs 6 lbs 2 oz.
Compared to the $2500 M1Pro Mac I just picked up...which everyone knows all the details about. It's party trick is transcoding 30 minutes of 1080p in 2 minutes (because I'm a luddite and that's what I was recording in.) it weighs 3lbs 8 oz. It's faster in EVERY METRIC except raw CUDA GPU power.
The three examples really can be compared or not, depending on the biases you have coming in. Compared to capability, the Mac Mops the floor with the Precision. The user experience is just streets ahead. But they're entirely different use cases, Paladin vs. Orc on your D&D spec sheet.
What is astounding is
just how bad the Precision is in the details. The biggest PC manufacturer using the processor from the oldest Processor manufacturer using the most supported OS in the world...and it can't sleep. (literally none of the 4 sleep modes are exposed to Windows from the BIOS). It comes with a 275 watt power supply you leave in the dock, which used two USB-C plugs to transfer the power, and if you used the 180 watt travel supply on the road, it complains if you try to charge your phone.
Apple attacked computing from the bottom up (how do we get our phone processor to scale) precisely BECAUSE what Intel was producing had a TON of technical debt it couldn't scale past, and a power budget that was horrific.
We can pick and choose and debate here in the muck and we'll miss the real details like 'supplychain inefficiency' and 'commodity parts make power management impossible' and 'Intel is seriously topheavy with management and spent too much time holding their improvements in reserve, squeezing the market for money as much as it could while AMD and Apple released better stuff sooner.
The missing mid-range desktop could be in the pipeline, or is may not. I think a LOT of 27" iMacs were sold because of the additional realestate by some people while others complained 'I'm not going to buy an AIO because I'll be throwing away a display if anything breaks and I can't upgrade the RAM, der hur'
With apple's upgrade program, I bought a MBP in 2017 for $1600...in 2022 I bought a MBP and the trade in value of the 2017 brought the price back down to...$1800. $320 a year for a Macbook doesn't seem all that bad, considering what it gave me in return. I didn't NEED to upgrade the Ram.
ETA: Wife had a 2013 MBP she upgraded to the new M1Pro...paid $1850 for it IIRC (more storage)...that's $205 a year for the privilege. It was doing all she really needed (except blurry backgrounds in Zoom, apparently that was too much to ask) and she swapped it as the battery was finally pooping out.
