I agree too -- and my son has been on Ritalin (or something like it) for three years . . .
My feeling is that they can be helpful during the years where the children are kind of immature, and in the process of learning routines and how to do things at school. I always tell my son that the meds help, but eventually we will take him off of the meds and he will do just fine. He has a tendency to rely on the meds, thinking that they make him pay attention more. Currently, he's on Strattera, and I think it does less for him academically, and more for his social abilities. Whatever it does academically is very slight, and I'm very interested in taking him off during the summer just to see if there's much difference.
