I can see where your friend's coming from - but I'd disagree up to a point. It's about which aspects you want to be in a state of flow. If you've used a computer for any length of time, then when you type you're not thinking about the act of pressing each key - you're probably thinking several words ahead of your fingers. If you type half a dozen characters and nothing happens on-screen, then they all appear at once three or four seconds later that would be an intolerable break of flow. (And happens more frequently today than it did when computers were literally 0.1% of their current speed.) If you're driving, you don't want to be thinking about the act of reaching for the gearstick or indicator stalk, but you do want to be thinking about what's happening on the road - so there you can indeed take "flow" too far. On the other hand, if you're performing music, your fingers need to be in a state of flow in order to free you to concentrate on the emotion of the music - yet that, too, would ideally be in a state of flow...
