That by itself raises an interesting editorial question. Apple (like most big companies) doesn't do things randomly re: high impact public communications like this. I'm curious what made the Mac mini a product that merited showing people doing things, with a computer that is tied to one location, vs. a Macbook Pro's comparative emptiness, for a computer that can go anywhere and be with anyone. It could be as simple as fun vs focus.
I imagine the Mac mini is really small now if it could be powered via USB PD then I think it’s no problem to put it in a backpack with a kb and touchpad then bring it home then to the office. This is because I notice there are many people just bring their MBP to the office then plug it to a big screen. The downside is just you can’t work anywhere like with a MBP, but the usability is mostly the same (to me)
