Apple Magic Trackpad 2/Mouse/Keyboard do work this way.

How? I always have issues switching my trackpad from my laptop to my mac mini and back... edit: nevermind, just noticed you said magic trackpad 2

They have a USB => Lightning cable. Plug it in briefly.

What does bluetooth not require support for multiple simultaneous devices. Have more than one device that won't let you connect more than one at a time.

The standard does support multiple simultaneous devices.

Your hardware? Not always.

I think it's a bandwidth issue. If I use bluetooth mouse, keyboard, and headphones at the same time, the mouse becomes very sluggish. It works totally fine if I turn off either the keyboard or the headphone.

I suspect that comes down to the protocol used.

I had no problem connecting a keyboard and phone (as modem) to a N800 back in the day, while also playing music from the phone to a pair of bluetooth headphones. But that was if i used PAN For the data connection between N800 and phone.

If i used DUN, either the music or the data would occasionally skip.

And that may well be what gives Bluetooth its reputation. So many choices for the various OEMs in terms of protocols/profiles, on top of a more complex air interface (channel hopping).

Given all of it, one may well be better off comparing Bluetooth to USB than wifi. As wifi is Ethernet over a single radio channel.

In theory, the Bluetooth protocol supports up to 7 devices connected simultaneously as slaves to one master device. However in practice, hardware support may be less than this.

I've found that microwave interferes very strongly with Bluetooth headphones

Both use the 2.4 ghz spectrum, so that makes sense - especially for bad microwaves. I had an old microwave that completely tanked my 2.4 ghz Wifi back in the days (very poorly shielded).

I still do. The ability to stream music in my kitchen is the reason I bought a 5GHz router.

That's nice, but the biggest UX problem with Bluetooth is still the pairing misery. It's 2016 and it's still nearly impossible to use any one Bluetooth device with multiple other devices. Try switching a Bluetooth headset from an iPhone to a Mac or convincing your car to switch from one phone to another. It's a huge mess and its not just a matter of the technology not working as designed. These are fundamental proble…

So true. At first I couldn't believe it, but it is IMPOSSIBLE to completely remove a paired bluetooth device from windows. After having connected my wireless keyboard to my mac for a day, I tried to reconnect it to windows. It fails silently and doesn't show up any more in available bluetooth devices. The connection to my mac obviously changed the pairing code, while windows still tries the old one. I googled for hou…

I went the 'new keyboard' route when I needed to repair my Logitech K811 - I now have two keyboards on my desk, one for the mac, the other for the PC.. Absolutely ridiculous, but saved me wasting a day of installation (and inevitably having to re-pair the K811 in the future)

As a matter of fact "more range" is quite the opposite of what I want from Bluetooth. Do I really need to have 5000 keyboards within range of my computer at the office, instead of the 100 I already have? I definitely do not.

I need the range. I routinely grab my phone when I'm cooking dinner and walk to the living room causing my bluetooth speaker to make awful noises.

That's where a wifi speaker is good.

So much negativity about bluetooth in these comments ... and yet I can happily say that bluetooth has really changed my life. Bluetooth headphones allow me to walk around and exercise without an annoying cord trailing the length of my body. And I can get to the office and sit down with my mouse and keyboard and just start typing without plugging anything at all in. While it certainly had early problems, I'm super hap…

Its because it is a complex combination of hardware and software protocols.

With wifi you have a single channel, and basically ethernet. On top of that anything goes as far as software is concerned.

With Bluetooth you have channel hopping radios, a pairing system for devices, and a bunch of profiles/protocols that define anything from basic serial data to encoding agnostic audio.
