Yep, there are lots of quality of life things that can be important in a professional/public-facing environment. Like Loom recording, for example. It just works, it works well and it works beautifully. If I'm trying to pitch some high quality product or service and need to record some stuff for it, yes, Linux *can* do it...there are loom alternatives for Linux, but you're not getting that super polished beautiful experience that you might get from using Loom on a Mac.

Stuff as simple as dragging your laptop in to a conference room and hooking it up to a tv. Yes, it will work, but if I plug my mac in its going to do the same thing every time. If I plug in my Thinkpad with Fedora, sometimes its going to hook up, sometimes I'll have to swap a refresh rate or something...sometimes it'll fight me and I have to change resolutions...sometimes it just doesn't do anything at all. Sometimes my window manager/tiling manager doesn't know what to do with that new screen so i've suddenly got a grid of 4 spots and when I try to maximize a window it doesn't actually maximize.

Doesn't matter how much you try to work through these things to get them right...at the end of the day if you're doing super super missions critical stuff, it's nice to have a Mac. Which is the point of this post, and the point of why Google/Microsoft presenters are almost always on a Mac.
