Combining a projector with a touchscreen and Android. Sounds like a bad idea until you see the person cooking while scrolling through a recipe on the counter.
In every kitchen of every home I've ever lived in, counter space has been a premium. A tablet affixed to the wall is a lot more practical for 1/20th the cost. But I suppose if you can afford this gadget, you are probably not wanting for kitchen counter space.
I mean if all you want to do is scroll through recipes in a browser, you could get away with one of those ridiculously cheap chinese tablets that cost like $30.
Or a first gen nexus 7, they're piss cheap now too.
Yeah I didn't find out the cost of this thing until sometime after I'd commented.
I guess if the tablet used leap motion like sensors for gestures that might work otherwise you'd have the issue of messy hands (common state while cooking).
