How many people carry their laptop around and put it on their kitchen counter when they cook?
Is this really a good solution for cooking though? The grid of holes for the speakers in the main column are going to get clogged with food spatters in no time, and they wouldn't be easy to clean. An iPad I can understand, since you can just wipe it off.
Why would anyone do that in the first place is the real question
And yet from what I can see on the product page this thing doesn't have video apps on it, and doesn't work as an Airplay video target, so you still end up with a laptop/iPad on the kitchen counter.
And what's wrong with moving a laptop around? They're designed to do that. The keyboard and trackpad give you great tactile control of what you're doing.
How many don't carry their phone?
