Got all the new bits together for the Mac Mini: a Satechi dock/stand incorporating a 512GB M.2 SSD to complement the Mac's 512GB of storage. The dock adds three USB-A data ports, one USB-C data port, audio out and SD/Micro SD card readers. None of the dock's ports can charge an iPhone or iPad, or connect an Apple SuperDrive but the back of the Mac Mini has a Thunderbolt 4 port and two USB 3.0 power & data ports, all unused. The Sound system is a combined 15W subwoofer/2.1 stereo external sound card and powered 3-port USB 2 ports. I just use one of those for a new 1080p webcam but I can use a mobile phone for that job.
A couple of months ago I bought a 28-in 4k monitor that looks really good. The last piece of the assemblage arrived today: a Magic Keyboard with Touch ID.
