If it’s the size of an Apple TV it will definitely only have a few ports. I can’t speak for anyone else but I’m personally fine with that, 1-2 USB-C, 1 USB-A, Ethernet, Power and HDMI would be fine IMO.

I think this was more of an issue when USB-C docks were less compatible and more expensive. Now you can get all the ports you need for $20. Just doesn’t seem like much of a big deal to me, when 90% of them are going to be connected to a monitor, wireless KB & mouse and WiFi and the occasional USB key or printer.
