Since 2018, I’ve essentially used my iPad as my primary computing device anywhere but at my desk. With the iPadOS 13.4 update, I started using my iPad as my principal machine even when I am at my desk.
My setup consists of either my 11” or 12.9” iPad Pro, Apple Magic Keyboard and Trackpad, and an inexpensive desktop stand from Amazon. I usually use whichever iPad is not in the stand with the Pencil to take notes or scribble out ideas.
When away from my desk, I am now using the Magic Keyboard for iPad, which has really come through in terms of giving my iPad almost completely the functionality of my Mac (even in tasks like coding and server administration)
