I've used a 12.9" iPad Pro as a laptop replacement since its release in 2018 and I'm happy about the particular series of yesses that have led to this latest OS release.

I've developed a number of workflows that would never work on a Macbook. For instance, I take handwritten notes with the device in my lap during a meeting, convert them to text, and add them to either project management software, or Roam (plug: https://roamresearch.com/).

The pencil is a total joy. I've taken up drawing and painting again and the more laptop-like the iPad becomes, the less I miss my old Macbook Air. In hindsight, it's the laptop form factor that makes less sense. When I need a full OS for some tasks, I use a desktop computer with commodity PC components.
