I gave the 12.9" 6 months. I used it most of the days at work, heavily relied on iCloud etc. I've now given up and have switched to an Surface Pro. While the iPad Pro does quite a lot of things, it still falls miserably short in others:
- only one Word document can be open at any time
- anything involving Files is slow and weird (files getting copied to and fro between iCloud drive and the app in use, every time you change them etc.)
So in short: still no decent file system, still no real multi-tasking, still a big iPhone.
I like it for PDF markup, but that's something the Surface Pro does equally well. So in conclusion (and this is coming from someone who relies heavily on the Apple ecosystem), if you need a laptop replacement, go for a Surface Pro. If you're a graphics artist, go with the iPad Pro.
Using word in 2018...? (Try Google docs dawg)
Really huge complaints you got here.
