I also disagree with the double computer approach.
Having two computers is an absolute necessity for me.
I lead dives where the majority of my clients are holiday divers, and the majority of these divers don't even have their own mask. I can abort the dive, but everybody would have a long face, and if the malfunction occurs during the first dive, what happens to the second dive? We run double dives.
I could use a bottom timer, but if I strap another device on my wrist, why not make it a full functioning computer? And as I mentioned before, my backup computer is in my console, so I don't even have to think about it.
