Given the alternative would be working while being sedentary, I think it's probably a fairly good (if odd) setup? I'm assuming he doesn't take the laptop like that when we he wants to walk to the shops at the weekend.
I would say the alternative is to not work 18 hours a day, but obviously that is his choice.

I wouldn't put my bet on that. He has said in the past that he uses his weekends to grid down his e-mail backlog. Rather, his graphs in past posts show him not talking on the phone on weekends, but still pretty constantly emailing.
