I had two events recently where I would need a mobile computing device. I used my 2015 Macbook Pro for one and my 12.9" iPad Pro with Keyboard for the other. Both times, my usual workflow included note-taking with Microsoft Word as well as accessing some docs via Safari, checking mail via Outlook, iMessaging, and doing other random things. I primarily used the iPad in Split Screen mode. Here is what I found: MacBook was slightly easier to find files, move them around, send them Having access to multiple windows (not just two) came in handy on the Macbook However, once you get set up with split screen, having Word side-by-side with Safari, Mail, or other apps is pretty natural on the iPad Pro. Was just as "productive" with this split screen set up. The iPad keyboard is performing well one year later The IPad 12.9" screen is just beautiful MacBook has become more "device-like" with each iOS version. I am surprised how much I use iMessage when sitting on my MacBook. I also occasionally take calls from my Macbook as well. This actually makes the iPad a bit less unique as I used to associate texting and phone calls with devices like iPads as opposed to computers. Both the iPad 12.9" and the MacBook pro can be pretty heavy when carrying in a bag. I don't have much experience with a 9.7" Pro, but it could be a good alternative. I also need to test the new Macbook Pro and the Retina Macbooks in a bag as well. In short, both machines performed very well for the tasks allotted. For this use case, I could see going iPad only - however, I also have to do things like remote login to my Windows machine, so I need to own a laptop. What surprised me a bit more is how many iOS functions MacOS is borrowing for the iPad (and iPhone), and how that is improving the Macbook experience.
