I've always had a hard time understanding what's so bad about the person who arrives being a clone, never saw the downside. Yes, I 'd definitely use it. One of the biggest hurdles in my everyday life is the "going there". When I was still working, the one thing I always complained about and what ruined my every morning was having to go there and return after. If I'd had the option to instantly teleport to work, I would have loved every day because I loved my work and I wanted to be there. Now that I'm disabled, I regularly have to cancel stuff like doctor's appointments last minute because my chronic exhaustion is acting up and I physically can't move my body there.
(If teleporting isn't available, I'd settle for a ship's computer core as a PDA)
