This is a silly argument. For the record I don't have a big issue with the USB-C ports. Also I didn't buy my USB 3 drives recently so why should I be mad at the companies I bought from? All the drives and perifrals I have that are USB 3 were bought within the last 2+ years.You're missing the point.
Most people do not have any use for the SD-card slot, hence they removed it. For those few that need it, there's an adapter for it - which should be much faster than the previously built-in SD-card reader.
For the record, connecting the camera via USB-C (either TB3 or USB 3.1) should be much much faster than SD-card.
USB 3 isn't a USB port.
The problem isn't that other companies aren't using USB 3, it's that they aren't using USB-C type port. Why aren't you mad at them for selling you out of date hardware (and if you're a photographer you probably even payed quite a lot for that outdated hardware)?!
Also I wasn't arguing the merits of USB 3 vs USB-C. I was simply stating that using the SD card was much faster than using WiFi and it was very convenient to have the SD card slot.
I think there would have been a lot less angst if Apple gave us 3 USB-C/TB ports, one USB 3 port and left the SD card slot in place for one more year. Give your users the opportunity to start moving over to the new ports without forcing them to. There's a lot to be said for convenience and having to have to not only buy dongles and adapters you now have to remember to take them with you.
Of course eventually my drives and other things will be USB-C but even one USB 3 port would would have given me more time to evaluate how to proceed.
