I have always thought that when business industry adopts the tablet and smartphone ( at industry-wide level, not just at small businesses ), for use in the daily business transactions ( for eg like they use the PC for a Point of Sale checkout, etc ) the smartphone and tablet will have entered a new phase.
I think at present, in spite of the advantages ably cited in the post, it is still a “consumption” device ( to borrow your term ).
But the advantages cited in post, are a key indicator to industry what they are missing.
