I saw that OP missed Calendar.app and I was convinced he was a liar. I regret that this is so aggressively ad hominem but Calendar has such obvious bugs I do not believe anyone - even the Calendar dev team - uses it.

It has two jobs: store events and remind you about events. Calendar gives notifications 10 minutes into meetings I'm already in (because my phone tells me about the meetings). It is unfathomable that this could have been released if anyone uses it.

The article is built specifically around the irony of that contradiction

I can't tell what the contradiction is.

I am a Mac user but I largely use the Google suite web apps, which I guess is the polar opposite of being a "power user".

What's contradictory however about someone using Mail or Calendar and being a power user? Is there a world of productivity apps that are much better designed than those? Or is anything below "I do everything in emacs" not a power user?

Saludos.

The Google web suite apps work quite well, in contrast to the Calendar app which I've never managed to get working.

I think the argument is more "How can a power user survive with something so flagrantly non-functional?"

Being a power user doesn’t mean that you have to run basic functionality like mail and calendar stuff from the terminal, and the GUI equivalents on Linux are not good enough
