M1 16'' has:

• 1 HDMI-port
• 1 charging port
• 3 USB-C ports

Back in the intel-days, lack of ports was a real concern, but I can't say that I've ever felt this with M1.

In fact, most of the common gripes with Mac hardware choices were resolved with M1. A sufficient amount of ports, real keys instead of a small touch screen for Escape- and Function-keys, and no undue focus on making the device as thin as possible at the expense of performance.

Add the fact that they are ridiculously fast and you've got yourself a very competent development machine.

I'd still hesitate at paying full retail price for one for personal use, but as a work device? I will gladly use one.
