"Technically, you're already a cyborg..."

Really, the only major thing keeping this from being at least mostly feasible today is the lack of a good way to do the user interface. Glasses-mounted HUDs don't seem to be production-ready yet. I guess if I were one of those people that always wore a Bluetooth earpiece, I could just route it through that, but I want something a little (ok, a lot) more subtle.
To be honest, it doesn't seem like a particularly useful definition of cyborg to me.
But, like all other definitions it can look useless when stretched to technically apply to specific situations (like the laptop-on-back example).
For instance, my refrigerator is technically interactive by the definition of reactive interactivity: "A message is related to one immediately previous message", where my messages consist of opening and closing the door, and the refrigerator's messages consist of turning on or off the interior light.
Saying my refrigerator is interactive is technically correct, but useless and silly. Still, the definition for reactive interactivity is useful and popular (at least in computer science).
I am curious what it is that qualifies a smartphone as an "exobrain" that also disqualifies a laptop?

Neither is "right" or "wrong"; they're both just definitions.
He more broadly introduced the idea of Tools as Prostheses. Telephones can be considered prosthetic ears: they can extend your power of hearing across continents. Ships can be considered prosthetic feet, they extend your power of travel, etc.
"Man has, as it were, become a kind of prosthetic God. When he puts on all his auxiliary organs he is truly magnificent; but those organs have not grown on to him and they still give him much trouble at times. ... Future ages will bring with them new and possibly unimaginably great advances in this field of civilization and will increase man's likeness to God still more."
PG wrote in How to do Philosophy: "Wittgenstein is popularly credited with the idea that most philosophical controversies are due to confusions over language."
Here the author fiddles with the word 'cyborg', bending its definition in a fruitless philosophical argument that benefits us not and humors most of us not.
