Well, as the pieces do not fit the storage inside the computer, it does make sense to extend the storage capabilities with an external box including... a paramount achievement... a slot for the pieces!
Joking apart, I am impressed by the push-sensitive squares behavior in this video. They appear to react with very little pressure from the pieces. I can tell mine (CG Pro) definitely can't behave this way: I need to use my fingertip straight in the middle of the square; or, if pushing with the piece itself (which I avoid to do), I definitely need to tilt it in order to push with the bottom edge, right in the center of the square. Pushing the piece flat on the square doesn't work
at all!!
