From Tablets to Table Top Computing

I know that I have talked about this before, but I do like the idea of surfaces becoming interfaces for computing, especially in public spaces such as coffeeshops where having enough space to work is a concern. Now, about this design – recently profiled at Yanko Design – actually removes the mobile from the equation. I don’t know that would work in this day where there are just too many mobiles in hand, but it does offer an interesting question – are tablets just a step to table top interfaces like this?
