There's a lot of people in this thread mistaking "Pro" for meaning "Developer." The iPad sucks for writing code. But there are tons of professional things you can do on it. I use it more than I use my laptop.

What differentiates the iPad Pro from the regular iPad is/was its high refresh rate display, which makes the Apple Pencil much more responsive, and True Tone color. These are definitely Pro-level features. Just not developer-Pro.
