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)
