Having a Yubikey permanently installed, I can say that on the 9370, I don't miss USB Type A ports, but I definitely wouldn't be using this as a daily laptop if it had one fewer (two total) USB Type C connectors.

That would effectively mean I have zero ports free when charging and with my permanent Yubikey plugged in. It's never been an issue in practice, but I also wish that Dell would remove the ambiguity and make them all TB3 ports.
