mt tables are fine and dandy and exactly what friends have built. There are several solutions for augmenting consumer panels for multitouch. This product is a bit further than multitough though.
The problem is that I see few reasons for playing boardgames, with friends, on them. You loose a lot of 'delight' factor. Physical pieces are very important to most people. I think if you asked two chess players if they would rather sit in a park and play in the sun with a physical set or play with a touchscreen inside, they would probably select the first.
I have played many digital board games, especially during covid. It's harder for me to concentrate on the game, it's less delightful. However for solo experiences and some extremes (gloomhaven) I do prefer digital games. (I also learned root digitally so that I could hurry my understanding of each faction before I played it physically with players who had a few games under their belt, and I play a lot of solo dune imperium because i love that game more than my friends it seems)
Can this product's support for physical pieces crack the 'delight in physicality' problem. Maybe. Like I said, I had some experience with this on the surface table like 15 years ago.
I think, in my experience at least, that they only time I've wanted a digital table is for TTRPG play for very tactical tables it just keeps the game moving faster than drawing a battlemap to put minis on. There is a reason I first started seeing them during D&D 4th edition where the combat was so 'on grid'. I imagine as we try out 'Draw Steel' we may revisit that more heavily as it's combat system is very 4E aligned.
The product is a concept that I want to work more than it, historically, has.
