It all depends on what it could do...
In saying this, I mean in terms of hardware, not software. Is it possible for me to embed some sort of RFID chip into the bottom of my LOTR or D&D miniatures and have the table keep track of their locations? If so, I'd buy it just for the miniature wargaming aspect alone. Being able to have hundreds of units on a table with statistics being automatically kept track of by a computer instead of by hand would imho make things more enjoyable.
I've found in general, games tend to be made simple because otherwise you do have to keep track of a ton of things with charts and multiples sheets of data. If you can make the data easier to handle, games can become more complex and interesting.
Plus I think it would be a blast to have some computer war games that you could control on the table with a top down view.
