SD cards are on the way out too.
They’re used pretty heavily by drones and SBCs, and quite a few people at work use them a lot.
Don't get me started on MagSafe return, they didn't even use the superior L-Plug they updated to.
Yeah, ****ed if I can see a good reason for that.
The HDMI port is brain dead.
I’m guessing there’s some major bottleneck that’s still not sorted out so they covered up by offering other ports instead.
Here I am!

I have a ton of A style flash drives lying around, and could not be bothered to get an A-C adapter .
I’m not crying about it, but it would be useful to have one on the 2.0 bus if there was room on the case.
The battery life is shorter
The 16” model hits the limit of battery capacity for air travel
I wonder if the ifixit tear down will show a USB-C hub hidden inside with a bunch adapters plugged in.
You jest, but the Intel macs did have a usb2.0 hub inside feeding the HIDs, camera, etc., though all soldered rather than plugged. IDK if the M1s do.
I am entirely happy with external PSUs. I still don't understand why anyone thinks they're a negative. The heat stays OUT of the computer body where heat is bad for performance, and if the PSU fries, you don't open the machine (and possibly replace the motherboard, in these compact machines); you just get a new brick. Desktop machines should be doing this, but mostly don't.
Also that makes it more convenient to connect directly to a UPS, without conversion losses.
still, I wish Apple would include a big capacitor in the iMac so when you get a power cut or some idiot unplugs the wrong cable it has time to suspend execution (assuming you have the disk space), or overwrite the RAM with random data (to defeat RAM freezing).
As someone who deploys a lot of iMacs into a professional environment, it's one more stupid thing we have to secure and lock down.
It does seem strange that they didn’t bring back the Kensington lock socket, especially on the iMac.
In the age of 15+ hours of battery life, why on earth are you plugged in while not at a desk for hours on end.
Matlab. They appear to have gotten a lot better in 2021a but they’ve had good years before and returned to form.
