IMO tactility was sacrificed in favor of versatility because we don't have a material that is both tactile and versatile and simulating such a thing is hard. And IMO it was a good tradeoff to make, instead of a tactile keyboard you have a keyboard that is infinitely adaptable. Maybe that changes with AR advances, could be gloves? embedded chips that send electrical impulses to your hands? an actual material versatile enough to be tactile and adapt to all the needs of a modern computing environment? But all those seem pretty far fetched to get into consumers hands in the near future and certainly back then. There are slight advances here with things like haptic engines in phones but it is still a far cry from the feel of a real tactile substance.
