Using a mac daily for work, no it doesn't. Some built in software features keep fucking up, external device or not. Like the "pause music" button, which stopped working entirely on my mac no matter if you press it on the builtin or external keyboard, the multi desktop which keep fucking up and putting apps on top of other apps that are fullscreen, making them barely usable...
We agree on the external device part though, it can decide to stop working with stuff you used for months for no good reason
