MS Office for iOS is very slick, and I use my iPad more than my Macs, but I turn to the Macs for serious MS Office work, like writing a paper in Word while simultaneously referring to Excel data, working on the companion PowerPoint, and opening multiple PDF references. Sometimes I need to make graphics for the Office apps with Affinity Designer. I haul my old 13" MacBook on trips where I occasionally need to do that kind of work while away from my main iMac. The little iPad is fine for simpler Office work. But the MacBook is aging, so now the interesting choice is between a light new MacBook versus an iPad Pro with external keyboard. So I will be interested in real world experiences from iPad Pro owners with similar needs. My hunch is that a smaller iPad and a new MacBook will likely suit me better. I can't see browsing and doing email in bed with the big iPad Pro. For heavier Office work I need multitasking between several apps, and I like interfacing with a mouse, and the MacBook gives me access to the file/folder system using Finder to keep everything organized and quickly find multiple files during a work session. Or am I just being a dinosaur and the iPad Pro/iOS has advantages I don't yet see?
