Ask HN: What is the intuition behind the Apple iOS Calendar GUI?

What kind of people find a calendar with just dots for your appointments useful?

It is not useful for people without many appointments because they still have to press on the dot to view the time and title.

But also it is not useful for people with many appointments because you just end up with a calendar full of dots. Also you can't see if an appointment spans multiple days because you just end up with a lot of dots.

Seriously what is the idea behind this? Is it just form over function or am I missing something here?
