This post brings up some important issues: many people on the spectrum have learning disabilities (especially those with PDD-NOS)
Even Aspies who are amazing in some academic areas, struggle with other simple things. My aspie son is brilliant in some areas but has trouble in others. My other son with PDD-NOS has a hard time with speech (he is 7) and basic skills (tying shoes, etc.), but we work very hard, and we have him reading almost to grade level, swimming, biking, etc.
brian: everyone has aptitudes and abilities, you only need to find them. None of us need to be exceptional--we only need to be happy. Once you stop trying to live up to other people's expectations, and learn to live up to your own expectations, life becomes a lot easier.
I struggled tremendously with math when I was a kid (seemed like a disability)--I didn't have my addition tables memorized when I was like 11! Even in college, it was hellish to get through a basic algebra course, and my GRE score in math was like 450 lol. Fortunately, I was always excellent in the humanities (English, history, fine art, etc.). Now that I have to teach my kids math, I have literally had to re-learn (or learn for the first time) things like geometry and algebra, and I am actually enjoying it (although I will never be strong in that area).
I also agree that IQ is imperfect and often of little value as an indicator. Richard Fenymen had an IQ of like 120--I think he was just a little smarter than that lol. When one of my sons tested low, I reminded myself not to get to caught up in psychometric testing. I have one friend with an IQ of like 145 who has trouble carrying on a conversation, because his knowledge is extremely narrow (computer science). Ask him a basic question about art, history, even politics, and he cannot come up with an answer.
