I don't see this as much as a portable tablet device that someone carries around, for just web access, music control, or holding and reading an e-book.
But a creative tool that stays around a workspace, probably most of the time in a stand... maybe a fair amount of time with a bluetooth keyboard paired to it.
But what I can really see it being, is a kiosk machine, or a portable business information interactive display.
iPads were introduced as consumer devices, but they have made great inroads as retail and professional data interactive portable devices... People don't necessarily write reports with them, but on a sales venue, customer service, or all sorts of paper-replacement duties...
With a card reader or other linked peripheral devices, they can replace some point of sale hardware.
TouchID, and apple's iOS management infrastructure improvements have some advantages for that use even further. Especially if TouchID sensor can be secondarily used for point-of-sale authentication by an API, separate from it's iOS embedded security features that are, and should remain walled off.
And the device is likely about the size of a 9x12 rigid clip-board, without the clip or the papers.
I can see road-warriors using this sort of thing with a cell connection, and a portable bluetooth keyboard, if they don't really need what a 13" MBP offers... and sharing information with others is a little less cumbersome on a slate than a laptop, when hand-held, without a table or desk surface to set it on.
I can see this going more toward management information systems endpoint usage, than people buying a iPad Pro in place of an iPad air or retina mini.
