very cool.

practically thinking, why not buy a large touch screen and use some sort of stylus instead of this white board?

in both cases, the user needs to buy special hardware. so i would think the costs would be comparable.

genuine question, not diminishing your work

A 85inch DIY whiteboard will cost about 500$ to make while the MSFT surface hub costs 19,999$.

comparably large touch screens are going to be order(s) of magnitude more expensive than this.
