Apple upgrades

[FredRydr]

This question is to those who have chosen Apple computers over the years.

I have two early 2015 MacBook Pros, which are the last notebooks made with USB-A ports. I've been resisting anything newer to avoid having to invest in dongles and adapters, and then there is that other factor: the unknown. Alas, the batteries are showing their age, and one keyboard is worn rather badly. I am comparing parts replacement and refurbished identical MacBooks, while the price of a new MacBook isn't all that far off and comes with warranty and support, etc. And they come only with Thunderbolt-3/USB-C ports.

How did you handle the change of ports and connectors? Do you find your newer MacBook incompatible with too many devices today? Or perhaps you see the problem that too many devices are incompatible with your new MacBook?

My analog brain chafes against the digital world....
