First of all, if you had a rare and awesome machine in your office that cannot be built anymore, wouldn't you be interested in preserving it just for the sake of it? Second, throughput and latency. Every ~10 seconds, a cab for ~2 people arrives at each floor. That's a bit slower than if you press the button, the doors of a waiting elevator cab open, you get in, and it takes you to your direct destination. It's a lot faster than if you barely missed both elevators, and they stop at every second floor on the way up and down to let people in/out. I wish we had one of these in our office.
