I'm not a professional photographer, but the 11in iPad Pro has been my main photo editing machine for a year now. The USB-C port and external drive support via iPadOS makes for a simple workflow using my DSLR and editing pipeline. If I ended up doing this kind of work professionally, I could see myself continuing to use this current workflow. I guess that would be real work too.
I don't know, but when it comes to editing photos out of my DSLR, I want the biggest screen possible (and matte), not some kind of tablet size glossy screen that reflects everything around.
Matte can be added onto an iPad with a screen protector. My iPad Pro is by far the best quality display I own. It’s definitely smaller than I’d want to be confined to all day, though.
Edit-I wish they’d release an oddly large iPad Pro. I think some interesting use cases might exist in the 24”,30”,higher screen sizes. Not unlike LFD displays.
external drive support - first time I've heard of this.
I generally have found it maddening that apple has set it up so that everyone has to "ask permission" before something is allowed on ipad/iphone/ipod. And they never let this happen before except to import from a camera (and the same camera adapter that worked on an ipad was not allowed on an iphone)
