They still can't figure out a non usb-A unifying receiver. Logitech usbc webcams still come with usb-A cables. In 2024 lol.
Logitech aren't just serving the Mac market, and the majority of computers out there still have USB-A (even MS's new Surface 7 devices still have a USB-A) - where they
do have USB-C it's usually a limited numberthat are in demand as display, charging and docking ports.
Even with Mac -
Q: which Macs don't already have webcams? A: Mac Mini/Studio/Pro
Q: what else do those have in common? A: They still have USB-A ports.
Like much of the non-Mac-specific world, Logitech are using USB-C where it was needed most: as a replacement for microUSB
sockets in mobile devices and small peripherals. Where a device has a captive cable, USB-A still makes the most sense.
Apple seems to have it back-to-front: pushing USB-C/TB3-only MacBooks long before the market was ready, but stubbornly hanging on to Lightning in iPhones and small peripherals...
(My Logitech webcam is plugged into a USB-A port on my USB-C
display).
Also, with the unifying receiver/Bolt dongles, USB-C presents a problem: with a USB-A connector, there's room for extra components in the "shaft" of the plug, so you get those nice, low-profile dongles and Flash drives which can be left permanently plugged in to a laptop. With USB-C, there's no spare space in the shaft and you end up with the USB-C dongle being
bigger than the USB-A dongle and sticking out too far for it to be left plugged in to a laptop - at which point, you may as well just use a low-profile USB-A to C adapter.
Logitech's assumption about Macs seems to be that Mac users will just use Bluetooth anyway, so they just leave the Unifying/Bolt adapters out of the Mac version (...but still charge the same!)
I just changed jobs and bought a personal laptop and only now realised that my old school Magic Keyboard and trackpad don't connect to multiple devices
Not sure USB-C is going to help with that. All that will change is that you'll use a USB-C to USB-C cable to charge & pair (which will probably be supplied) as a direct replacement for the currently supplied USB-C to Lightning cable - the functionality won't necessarily change. You can already use the Magic Keyboard as a wired keyboard - one of the few
nice touches on the Tragic Keyboard (don't know about the Trackpad, the Mouse obviously not).
Using USB-C on the Magic peripherals makes sense - there was never
any good reason to use Lightning on
Mac peripherals (USB-C was already available when they launched) but it really doesn't make a big difference. I don't tghink there's any conspiracy theory needed to explain why they haven't switched yet - it's just a low-priority thing that they haven't got around to yet.
Of course, Apple
could take a leaf out of Logitech's book and design new peripherals that can pair with multiple devices (and a mouse that can be used as it is charging, but that's quite independent of USB-C.
