When I ride by myself I tend to push it wether I have my computer or not. I do enjoy the more relaxed rides but those are done when I ride with my wife and a friend that goes with us (they tend to be a fair amount slower than me). I keep my computer on when riding with them but more or less just to keep track of distance and time. On the slow rides the data is useful in helping me plan the next ride (lets me know if we can go farther, or need to shorten the route or plan for more time and breaks).
