I have a second hand, first gen iPad pro. I use it as a colour pdf reader for academic papers and for carrying a large number of books around for teaching students with the ability to look stuff up on it. It's jailbroken and I enjoy being able to SSH in. The big screen is good for looking at high res images (part of my work) but fundamentally I'd never buy it at full price. I don't find typing on it easy at all and I prefer a real pen for real maths.
