I recently discovered that the signing feature can use an associated iPhone or iPad (with stylus!) as the signing device where you write your signature.
This is sometimes true on a hardware level, too. For example, I was using a Bluetooth Plantronics headset for voice chat on my iMac G5 in 2005 because Macs had come standard with Bluetooth for a year or two at that point. It wouldn't be for another 5 years or so for midrange-and-above prebuilt laptops to start coming with BT and it wasn't until the past 5 or so years that enthusiast motherboards and desktops started reliably coming with it.
The latest feature like this is Thunderbolt, which is starting to become more common on generic laptops, but is still surprisingly hard to come by in prebuilt PC desktops and enthusiast motherboards.
I've been using Thunderbolt since TB 1, was it 2011? It was mind blowing at the time. With the original Apple TB Display it was so great to be able to just connect to the display and also get ethernet and my laptop charged.
I want Apple to have healthy competition to keep them on their feet but they often just run a different race.
(I have LOTS of complaints about Apple stuff, I am not a fanboy, but as a technologist, I like that they push the envelope and raise the bar in many areas).
I'm especially glad that we seem to be out of the Jony Ive era where every design decision was a head-scratcher.
When you buy a Logitech bluetooth mouse or keyboard, it comes with a proprietary 2.4Ghz dongle as well. Unless it's the mac version, that doesn't come with an extra dongle. Presumably because bluetooth is almost guaranteed to be available and work on a mac. It will even work when you reboot into recovery mode.
AirPods plus a mac work well too. It's usually not a fun experience when using bluetooth headphones on a PC and the microphone gets activated.
Regarding thunderbolt, it's disappointing it's not on every system. I use it all the time to transfer files between macs using static IP addresses.
I have to say, the bluetooth experience is one of the worst pain points for me on macs these days. I'm always connected to the wrong source. Or it's connected to two sources, but playing sound from the wrong one. Or I skip an ad on youtube on my macbook and my headphones switch source to my phone in that instant. Or it just doesn't want to connect at all, and I end up turning BT off and on. Or one bud connects and the other doesn't. Or I walk out of range of my computer and my headphones connected to my phone tell me I've disconnected every ten seconds forever. Or I try to hit the pause button on my headphones and they think I want to skip forward 6 podcasts. Or my phone rings and my headphones are connected to my computer, and I can't switch them fast enough, so I just have to take them off and answer without them. Always something.
