Weren’t we having this discussion when they dropped the floppy drive? Should they keep USB-A forever? When is it ok that they drop USB-A? The original move to USB-A was met with resistance to people then that were angry that suddenly their ADP or other older devices wouldn’t connect — but then device markers saw the advantages of USB and quickly moved to embrace it. They are starting to see the advantages of Thunderbolt 3 and eventually, USB-A will go the way of the serial port — but not without the requisite hang-wringing and “get off my lawn” first. In 3 years, nothing but dollar-store junk will still use USB-A.
