My experience traveling with expensive electronics is that it's difficult to keep track of them ALL of the time. It's fine to be aware and in control 98% of the time, but it turns out that's not enough. Only bring what you are willing to lose. I lived in Spain for a long time and spacing out on the metro one day a fellow slit a hole in my backpack and very nearly carried off my laptop. I didn't even notice the rip until I was home.
