It doesn't just work. If I get a wireless keyboard and mouse that "just works" in theory but in practice does not "just work" always, then that's a load of hassle that far outweighs any advantages it may have.
In essence, the drawback is the lack of trust, because the promises of wireless that "just works" have been repeatedly made and broken. Fool me once, shame on you, fool me twice... I won't allow myself to be fooled again by such promises.
So if you do have a system that just works, then I'd refuse it on principle (because I simply won't believe your claims, no matter what you say) until at least multiple years have passed with it being widely used resulting in a general consensus that it really does just work in all cases, without there being e.g. a 1% minority talking about all the many edge cases they encountered where it turns out that it does not actually "just work".
>I won't allow myself to be fooled again by such promises
I get the sentiment, but its kind of silly in practice. Things improve almost constantly.
Just trying to say I have been using a wireless mouse and keyboard for years, they have never given me any trouble. In fact, even less trouble than wired peripherals have given me over the years. Maybe you should bend your rule and try out some modern stuff if your previous experience was not a modern device.
They don't "just work". Whether it's Logitech or Apple mouse, my cat laying in front of the pad breaks the connection. (Not enough to disconnect, just adds jitter)
When playing games, wireless keyboard/mouse introduce enough latency that twitchy platformers or competitive shooters are impacted. (Unless you buy super expensive game-oriented device)
Bluetooth devices are terrible... by design because of Bluetooth and its problems. Special dongles don't function well when plugged in on the back of monitors and sometimes need manual "replug" to register after a reboot.
I hope this doesn't get treated as an advertisement since I'm not affiliated -- but do try Logitech G900 (also branded as Chaos Spectrum) or G903 mice.
My wife played competitive Overwatch for a few months some years ago and she said the mouse feels exactly as a wired device. I play Quake every now and then and can confirm the same. Best mouse we ever used, we have 4 at home.
It has the added benefit that it disables its wireless circuitry when you plug it in -- it both recharges itself and becomes a wired mouse.
(Yes, both mice can be viewed as expensive. But we took the plunge to invest in reliable periphery and have only been happy with our investment.)
Wireless is subject to interference and introduces new security concerns. They run on batteries which you then have to replace. They tend to cost more. That's a lot of trouble to avoid a two foot USB cable.
Latency -- You'll never get a wireless mouse faster than fiber-optic, since the computer screen would interfere with optical wireless transmission ;)
I jest. The real theoretical issue is pairing (portability). I can't think of a wireless solution that provides all three of:
1. No dongle. I don't want an extra thing to keep track of.
2. Fast and convenient pairing ("plug" and play). Connecting to a different computer should not be a hassle.
3. Secure. Device must only pair with computers of my choosing.
Dongles, WPS buttons, and bluetooth number confirmation are existing solutions that provide any two. A physical plug combines "connect" and "authorize" steps, neatly sidestepping the issue.
The closest thing I could think of to solve this would be a standard, as ubiquitous as USB, for wireless connection: each device has a code that serves as protocol negotiation, identification, and authorization. So you open up a "connect a device" dialog on the computer, type in your device's code, and the computer automatically discovers the device and pairs with it. But even this is a compromise on both usability (another thing to remember...) and/or security (it could be printed on the device, like a serial number, but then...).
And, of course there's the myriad practical issues mentioned elsewhere in the thread. I think if they were (truly) solved, I would buy wireless devices for my home setup, to do away with cable management, and keep cheap wired ones for use with other people's computers. I don't anticipate this happening for at least a decade or two.
I may be misunderstanding your point, but couldn't the USB-based pairing that Apple uses for their keyboards and mice solve functionally all of these issues?
There's no dongle (they're bluetooth) and pairing is dead simple (plug it in once and it's available everywhere). I don't think I've ever seen a security analysis of their peripherals, but the potential for a mitm attack on the keyboard seems like it would be equal to or lower than a wired version.
This assumes, of course, that you're using Apple products across the board but it is a solution nonetheless.
D'oh! Yes, if I understand correctly (I don't use Apple products[0], so this is the first I'm hearing of it), that would solve the issue, since USB cables are common enough that I wouldn't need to bring one with me just for pairing. I'll still be sticking to wired for practical reasons, for the time being, but maybe those will be fixed sooner than I expect :)
[0] I swore off of walled gardens after an unsavory experience regarding EOL of the 1st gen iPod touch — Apple effectively bricked my working hardware by taking all apps for it off the app store.
It’s not practical when you have to do it several times a day and having a cable lying around and having to connect it sort of defies the purpose of a wireless keyboard/mouse.
Same applies to Bluetooth speakers by the way, pairing is just horribly annoying. I wish they’d just replace the volume buttons for a dedicated pairing button instead of having a different way to pair on each device (do I hold the volume or that other button? Was it 3 or 15 seconds)
I must admit having several computers is a bit of an edge case, but still.
For a keyboard, wireless buys me nothing but introduces a number of new potential issues.
For a mouse, wireless buys you some convenience and freedom of movement. However (and this is slightly niche so it really doesn’t apply in general) I use a trackball, so the wireless advantages are 100% negated.
Being able to move around (several monitors) and easy use of a standing desk are some advantages. I have a workstation under my desk and a laptop that I frequently hook up to my monitors frequently.
Philosophically, wireless is just going to be more complicated than wired. Say I'm sitting in front of 4 computers with 1 keyboard. Without interacting with the system at all, which computer is connected to the keyboard? With wireless its difficult/impossible to tell whereas it's fairly clear with wired.
It is! In engineering, as discrete from science, the point of theory is to know what is going to happen in practice. If theory can't tell you, then it's useless for practical purposes. If the theory is ignoring important aspects of reality that make it useless, then what's the point of theory?
Eg In theory we can move faster than light, we just need a source of infinite energy. In practice, "infinite" is an impossibly large amount of energy, so any theories that allow for faster than light travel are only interesting for entertainment/theoretical purposes.
For wireless connections, the gulf between theory and practice is just too large, so theory remains theoretical.
It's more stuff that can go wrong. I understand why you would want a wired mouse for a weird setup where you don't want a wire from the mouse or /can't/ have a wire from the mouse to the machine. But I don't see the need just like I don't see a need for wireless charging or wireless hdmi or wireless southbridge.
Wireless hdmi: Though it’s technically not the same, think of chromecast, I think it’s nice to be able to stream stuff on the tv without the need to physically connect it.
Since power cables are still the easiest to find in a normal household (compared to any cables that carry data), I’d argue that anything except for these can have at least a little bit of value if it’s wireless and done in a convenient way.
The problem is unnecessarily occupying wireless spectrum for devices than can use a cable.
You can make a wireless monitor. I expect it to work just fine in a home environment. I expect it to fail in all kinds of crazy ways in an office with dozens of these monitors side by side among other devices also using wireless communications like phones.
Stopping to work in the middle of a live presentation or in the middle of a game. My mouse is excellent, I love it but I have a magnetic USB cable next to the mouse pad for the times where I get a warning 10 seconds before shutting down.
Maybe I am a stupid layman but isn't that mouse pad basically a low power induction cooker? Am I superstitious to not want to keep my hand on an induction cooker for hours per day?
Potential interference, crowded spectrum, battery required, extra weight due to the presence of battery, and if the encryption is weak then you have a signal broadcasting all that you type in the vicinity which could be a security nightmare.
I didn't realize people had such low expectations for "just works". Getting a reliable signal for such a short range and low bandwidth is obviously possible, as is using proper encryption. Batteries can be light, with the weight compensated for, and charge wirelessly.
The reason I said "just works" was to avoid an exhaustive list of issues that have already been solved in other products, or could be solved with some effort.
