I saw a fridge that had an app so you could control it from anywhere.
My requirements for a fridge are remarkably simple, to the point the only practical use I could think of an app was alarm that I'd left the door open or something.
(If this particular app did have a door-open alarm, it wasn't on the list of features. It did say you could adjust the temperature from your office. A location I'm often worrying about the fridge.)
Who decided to call useless ideas an "innovation" is beyond my understanding.
Ideally, as I print photos mainly, I get more then 4 colors and decent color management.
Added bonus for scanning (with or without document feeder).
Not much else there. Pay-per-page subscriptions are ok, by the way, price wise for home office use.
Then it comes down to innovation in the fields of color management, ink mixing and print heads and paper handling. And inks, of course.
Anything else is just pointless, and nothing I would call innovation.
