No one is saying Android users are more intelligent. Apple products are dumb downed for the masses, and that's why they're popular. One button to push, they way they restrict you from doing many things, lack of options, etc. Truthfully people are too stupid to leave well enough alone, so when the ability to tinker is taken away from them, they think it's a better product (i.e. easier to use).
I guess if you look at that way, Android users probably are more intelligent. Not EVERY user, just as not EVERY iPhone user is dumb, but probably in general.
