well, here is the thing, I just got my first smart phone last August, i caved, and a lot of terrible side effects, but one thing i did notice, I am spending a lot less time staring at my dual monitor computer screens, now do I spend more time looking at a screen before I had my smart phone, I'm not sure, but there is a lot less desktop time and no laptop time any more, just thought that was an interesting perspective on this topic
