I've got a couple of large scale iPad/App deployments (medical and Federal sector), where the iPad, being used in "standalone" mode (one use case is just terrific with the app + pencil + camera) is greatly preferred (both from the user experience and the operations/management/security consideration) , but as part of the use case, there's some non-trivial amount of "office chores", that are really improved through the use of a physical KB (and I would suspect, an integrated TP).
I'm the same way, when I'm occasionally on the road, I really prefer the iPad, but I have situations where I'd like a physical KB, for me, it's sort of an "iOS First" stance, but I recognize some tasks are improved with a product like this.
I'm a dev/designer/architect, but I don't need those tools away from my desk, which is why I went from a pretty stout MBP, to an '18 Mini.
