I know some people will “everything is usb-c now!” except everything isn’t, so stop.
I have a ten year old Mac Mini on my desk that has two FireWire, four usb, an sd card reader, and Ethernet. I still want most of these things (though, of course swap FireWire for some number of usb-c). I don’t want to HAVE to buy a dock for this machine.
In hearing that it’ll be smaller, my initial assumption is Apple will do the Apple thing and arbitrarily reduce the number of ports while saying “if you want more here’s the Mac Studio that’s way more expensive!”
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.
