...only if you connect a TB3 display (of which there are only a handful on the market, including 5k displays that use both streams anyway). Or a TB-to-dual-DisplayPort adapter (another $100 and quite a big box because it contains a full TB3 controller - older/cheaper ones still rely on DisplayPort daisy-chaining which doesn't work on Macs) or a TB3 dock (...after buying a Mac Mini because it was so small, neat and had an integrated PSU... Docking stations are for laptops - if your desktop needs one, something has gone wrong).
Now you're being silly: TB3 has 100x the bandwidth of USB2, and far lower latency. Half the point of Thunderbolt is that it has more than enough bandwidth to support multiple devices on one port. Meanwhile, printers may not be a good example, but there are plenty of USB2/3 devices (which don't have bandwidth or latency to spare) that are best connected to a top-level port rather than a hub. Step 1 in USB troubleshooting is to connect it directly to the computer and not a hub...
You misunderstand - I was suggesting that if/when computers start offering 8+ TB3/USB-C ports, dropping single-use ports would be less of an issue.
We've strayed off he point here - the argument about whether its OK to just have TB3/USB-C ports belongs in a MacBook forum. I'm not unhappy with the port offering on the Mac Mini - this started because someone else was touting "4 TB3 Ports!!!" as a killer feature of the Mini compared with PC alternatives.
Some of those alternatives - like the Intel Hades Canyon NUC - may only have 2xTB3 but because they also have a shedload of "single-use" ports they'd still have 2xTB3 free for sexy future devices after I'd connected up all of my non-TB3 devices. On a Mini, I'd still be able to connect all of my stuff, but I'd be lucky to have even 2 TB3 ports available for expansion - unless I added a hub (which starts to defeat the point of getting a Mini).
The Mini may look a lot more attractive if/when Apple or third parties come out with some matching "stackable" peripherals (maybe a TB3 enclosure with a couple of M.2. drives, a pair of DisplayPorts and some USB...?)
I'm the one who shouted "4 TB3 Ports!!!"...
It's the only distinctive thing in new Mac Mini I found (also in iMacPro & MacBookPro). As I couldn't find ANY motherboard offering that, I thought it could be relevant to someone (not for me; I don't need them for now).
But theluggage has given us a lot of info. I've learnt some, and think he's right...
(...but I still wonder if something "marvellous" can be done with four Th3... or Apple is just future-proofing the Mini, to stay unchanged for other four years...)
