This is a most excellent place for technology news and articles.
I have one of the more recent models. When I sit down at my desk, I just plug it into a Thunderbolt dock anyway, through a single port. All those extra ports just sit unused, despite having a USB-A keyboard and mouse, Ethernet jack, and 4k monitor at that desk. Plus the dongle provides power to the laptop.
I do use the SD reader from time to time, though. I used to have an external reader that was a bit unwieldy on the laptop, but it was also a requirement from when I was shooting pictures on a CompactFlash, which has never had a built in reader on any laptop.
