Good for you. That doesn't mean other people where not using the ports. I use the SD card slot as a semi internal storage space effectively going from 128GB to 256GB of storage. I use the HDMI for testing the transmitters and receivers at job sites to make sure they are active. I use the USB A connector for connecting to the equipment to set up the components.
In one foul swoop, all of those ports are gone, and the new MacBook Pro no longer meets my needs. News flash Apple, you don't dictate to me what ports I use. The machines I work on dictate the ports I need. If you drop the ports on your machines I will be forced to find another brand that puts the ports on their machine and use them instead ... which is everyone else.
In effect, previously Apple was dictating which ports everyone used. Few of the ports on the old machines had dual purpose - so those chosen by Apple were what everyone got. HDMI on a laptop is a sign to me that it's not a serious work machine, because displayport has been the business standard for years. DisplayPort could be easily adapted to HDMI or VGA. Not so with HDMI. Thunderbolt 3 is a further refinement of that type of port. You need HDMI now? Buy a new cable. No dongle required.
Anyone who is doing serious work on a computer will have a bag of adapters they carry with them. All that changes with these new devices is that you need some new cables - just as has been happening repeatedly since the dawn of the computer.
