I agree that most that use the treadmills get very little benefit, but I like to run 4-5 miles up an incline, and while it isn't as good as my normal runs, I would argue that there are still plenty of aerobic benefits and muscle groups being worked. Using a treadmill I was able to lose about 15 pounds (I've since lost 10 more) and I was able to get my endurance and my speed up in a relatively short period of time.
