Desktops and rack mounts you tend to leave that RJ45 plugged into the back all the time. As a result, "no link" is a rare error condition. On the other hand, laptops are often sitting around with no RJ45 in sight. Being able to detect "card present but no cable plugged in" can be useful in startup scripts and the like, so you can do something like if [ link-is-up eth3 ]; then ifup eth3; fi and avoid throwing nasty error messages (and even worse, timeouts) trying to bring up the card if there's nothing plugged in. There's no sense in trying to do the whole DHCP thing (or whatever you need to do) if you can tell beforehand that it will fail....
