If it doesn't cost too much, I probably would buy it to replace the stereo HomePod mini pair we have as our living room sound system currently. OTOH, our old sound bar took up a lot of space that we've enjoyed having back since switching it out.

Seems pretty good, though it is fairly expensive. Hopefully time will bring more retina display options.

Regarding the color, do you have a colorimeter you can use to calibrate the display? That might help bring it more in line with the built in MBP display.

Will we be able to get FSD that is, statistically, safer than the average human driver? Probably. Will it ever beat the best human drivers? No way. Humans think in a way that computers cannot replicate, no matter how fast they process information there is no way they can make judgement calls. I'll always be more comfortable driving my own vehicle or riding in one driven by a professional human driver than I would be in a self-driving vehicle.

"...just got even creepier thanks to AirTag."

You mean thanks to tracker technology? They could be doing this with any of them, and probably are using other trackers, too. We just found out because AirTags are safer than some other trackers.

Also, report the tracker to the police only after you've planted it on your ex's car 

I agree with others here that parts pairing is an unreasonable solution to the problems of device theft, hacking, and repair with cheap parts. These are still problems that could be alleviated by other means.

One option is that Apple could make parts pairing an on-by-default option that power users could turn off if and when their phones need repair, possibly with the caveat that use of non-Apple parts or unauthorized service providers will void any remaining warranty. This would still prevent most theft and people who don't know what they're doing having their phones messed up with substandard parts, but it would allow the option for those with the know-how to repair their own devices with any parts they deem suitable.

Another option would be parts blacklisting: let devices use all Apple approved parts, but once a device is marked as stolen all the parts that might be swapped into other devices are added to a blacklist that would make them non-functional when installed in any device connected to the internet. They should still function in the original device, as Find My needs to still work to track them down. Once a device is confirmed returned to the rightful owner, its parts would be removed from the blacklist.
