I'm 26 and the iPad Air and iPad mini do not appeal to me but I own an iPad Pro and I am enamored with it. I use the iPad Pro at my full-time job as a Software Engineer at Microsoft. I get a lot of mileage by taking notes on it in OneNote and preparing/reading documents from the other Office apps. I also use the iPad to listen to music with Spotify (my headphones have trouble connecting to my work PC). Outside of the office, I use the iPad as a second screen for my Windows Laptop with Duet (

My major complaint with the device is the poor IDE support. I think I would love to be able to use it with Visual Studio Code as it is much easier to carry around than my laptop and I don't need the powerful laptop all that frequently. It has basically replaced all of the functionality of my laptop except for my development work.
Hope you find that helpful.
