Just to make sure I understand you, I need to install something to have great UX on Windows? You see how quickly we getting there, default UX on Windows is crap but you can install x,y,z. This is exactly why I use MacOS because I am tired of tracking what exactly is doing those things I (and many other people) need on a daily basis on Windows.

So where is a calendar widget in the OSX that allows me to see my events when I click on it ? Why do I have to install itsycal when windows has it built in to the os date time widget which is superior to OSX ?

It's a ridiculous argument and I don't see why screen capture should be a part of the OS other than you expect it from OSX.

Besides the UX of OSX screen capture is inferior compared to Greenshot - much easier to determine the capture target and way more options - I don't want to spam my desktop with screenshots.
