Because almost all computers still have USB-A ports, even if they might also have USB-C ports. So, the peripheral manufacturers stick with USB-A, since if you have a Mac, you almost certainly also bought a hub or adapter cables.
It’s the same reason there are 1000x as many USB-A Flash drives as USB-C ones.
I typed “USB-C wired mouse” into Amazon and got a bunch. What’s the problem?
He’s looking for wireless
Yes, but USB-C flash drives are made. I don’t know about other manufacturers, but its been over 2 years since Dell went to all USB-C ports, at least on the XPS line. Dell sells a lot of computers, so it just seems odd that Logitech and other large peripheral makers currently offer nothing.
I would understand if they were currently priced higher or limited to fewer models. But nothing?
Buy a standard USB Hub. Connect to laptop with adapter cable.
Do Hub’s slow down Gamers?
I want a wireless mouse.
I don’t want a cable. I don’t want a dongle. I dont want a usb-a to usb-c adapter. (I already have an adapter) See pic a few posts above to understand why I dont like it.
Does it have to be Logitech? The peripherals market has mostly been overtaken by no name manufacturers and gaming niches.
Logitech hasn’t really been able to keep up for quite a while now, but there are a bunch of both named and no name brands that do make what you want. It’s a mouse, not some super fancy chip… if you want something slightly fancier, can’t one of the gaming companies do it?
Or that Matias company from Canada with their tiny dongle?
Edit: For what it’s worth, I used to be an exclusive Logitech fanboy. But they stopped really innovating probably ~10-15 years ago, and the smaller manufacturers quickly took over. These days, SteelSeries makes stuff as good or better than Logitech ever did, at a fraction of the price, and with better UX, IMO.
Their glowing gamer lights do drive me a little bit crazy, but it’s just a one-time disabling in the app so it’s not too bad.
It probably comes down to the fact that if a computer has USB-C connectors, it’s a modern enough computer to also have Bluetooth built-in. If a wireless mouse included a USB-C receiver dongle, chances are that it would not be used. It wouldn’t be needed. The customer would just connect the mouse to the computer’s native Bluetooth network.
…and yet here you have multiple people who WANT a USB mouse, even if that same mouse had Bluetooth built-in. We exist, I promise 
Most (all?) wireless Logitech mice and keyboards come with a “unifying receiver”. You can also buy one from them if you lose the one that came with your keyboard or mouse. So why doesn’t Logitech sell a USB-C version of the thing?
This one sure looks like it has a usb-c 2.4ghz receiver.
I would guess it’s because the Logitech devices support Bluetooth in addition to whatever protocol the Unifying receiver uses. If your computer doesn’t have Bluetooth, then you have to use the Unifying receiver since there’s no other way to connect. But if the computer has Bluetooth (which most USB-C computers would have), then the customer would connect the device over Bluetooth.
(Deleted. Will create a linked topic instead: Bluetooth sucks. Why isn't there a better wireless protocol for peripherals?)
Except Bluetooth sucks. It’s laggy, it’s unreliable, and if you have multiple Bluetooth devices, it can be really annoying to get it to connect to the right one. (Yes, i have multiple laptops as well as a phone. I really fight with my favorite Bluetooth headset to get it to talk to the laptop I’m currently using.)
In general I’m happy with a touch pad. But any time i need better control than a touchpad can give me, a Bluetooth mouse isn’t going to cut it. I have also been shopping for wireless mice with USB-C dongles. I found one that works okay. It’s not as nice as my gaming mouse with a USB-A dongle. So I’m still in the market.
One issue is that the USB-A port is large enough to hide some of the electronics in it, and the USB-C port isn’t, so the USB-C single will stick out more. It’s still worth it, and way better than an adapter.
So I’m about to follow the links in this thread.
There are tons of USB-C flash drives, that’s easy to find.
I bought a MacBook pro specifically so i DON’T need a nest of adapters and hubs. Is it that weird to want a decent wireless mouse, too?
Ditto
The volume is not there yet. You’re describing a niche use-case:
It’s a reasonable request, but not a common one.
There are a lot of costs to creating a Type C version and if the volume isn’t there, it won’t justify it for a low margin item. You can’t charge more, because most people would suck it up and use an adapter rather than pay $1 more.
Flash drives are just ahead of the curve. There’s probably a sense that Type C will do faster data transfers, the use-case includes desktops and servers, and the drive doesn’t permanently use a port like a mouse does.
I was so happy when they finally brought back the HDMI port and function keys. I love my M2, but if they ever add back a USB-A port, that’d be an immediate upgrade for me. I don’t care if it has to be 1" thicker and 30x uglier… I miss my USB ports, if only for interop with the Windows world (which is every school, hotel, conference, non-tech business, etc.) 
Edit: I hope they make the Air the svelte mainstream computer it already is, but turn the Pro into actual workstations with built-in ethernet, USB-A, etc.
Same.
Also, I’d be grateful if people stopped saying, “just use Bluetooth”. It’s not adequate for a number of reasons already stated.
I think the existence of the MacBook pro suggests otherwise. Or, at least, that there’s a significant market of people looking to avoid adapters and dongles hanging off their laptops. Because let’s be realistic, the Air is powerful enough for almost everyone. The upcharge for a Pro is mostly to get the extra ports. And those machines are selling briskly enough for Apple to refresh them every year, so i would think there’s some market for peripherals, too.
And it’s not just Apple moving away from USB-A. My large Dell laptop doesn’t support USB-A, either.
I will be shopping for a new laptop and will be following this with interest as well. Why oh why are there so few options for wireless USB C mice? Not a fan of bluetooth connections.
