They are also a major proprietary hassle, whereas with Bluetooth and a Logitech K380 keyboard, which is cheap, readily available everywhere and reliable as heck I can switch between three machines at the press of a button.
I use that and an M720 Bluetooth mouse to switch between two work machines and a personal one on the same desktop, which is something you just can't do with the Logitech Logi Bolt dongle - even if you buy multiple ones.
Also, I've been using this setup with Macs for ages (that's one of the machines above), and never ran into the same problem.
Pros and cons? With the Logitech (and others) dongles you can also just plug them into a KVM and swap that way which isn't an option with Bluetooth, the device specifically has to support multiple devices.
But to use a KVM you have to have some form of commonality between devices (one of mine only has USB-C ports), plus you have to have all the cabling. And most consumer KVMs only take 2 outputs.
I'll take Bluetooth _any day_ over having another mess of cables, another box, and what boils down to less ease of use.
I use a USB C hub with my KVM for my laptop. The hub takes the KVM USB A cable and the DP cable. One cable connects the laptop and I can switch PCs with a touch of a single button. I don't like switching inputs on my monitor manually through the OSD. You can get KVMs that do 3 or 4 computers with multiple monitors, although granted they do cost more. Again, pros and cons! I find it pretty slick though.
I added a small udev rule to send a "change input" dcc command to the monitor when my USB switch connects or disconnects. The monitor has a USB-C input, and I connect the USB ports it provides to my USB switch.
Cheaper than a KVM, though it only works if the computer that has the rules is turned on (that monitor accepts commands from inactive sources).
If somebody knows a ready-made "reverse dock" (USB-C dock connector -> USB-PD out + DP in + USB device), I'm all ears!
Entirely reasonable stance. Previous story[0] about keyboard “security”: 8/10 tested were vulnerable to sniffing or injection. A handy summary table someone put together
