I'm going to vote for no on that; at least for me, running takes a lot of focus, to the point where ditching the iPod helped me become a stronger runner. I had always run with music before, but I found that if I focused on the run itself, I could push myself harder. Weightlifting and climbing work the same way, in my experience, and I can't imagine that my limited martial arts training would have been any better if I had something else to focus on other than not getting punched in the face. Our society is obsessed with trying to do everything at once, rather than giving full focus to each activity in turn. Personally, I'd rather that technology reduce the busy work, so that we can focus more directly on each activity, rather than trying to amalgamate them together all the time.
