Default A40 better with the Aiaf on or off?

I have read some post saying that the A40 achieves better focus with the aiaf off. Since I really don't understand what the aiaf does for sure, thought I would ask what you folks think about it.

Also, I like to take outdoor scenery type shots. Is one method better than another for achieving proper focus and exposure when shooting landscapes? Thanks for the help!

From what I have read on other posts, the Canon will probably choose the object closest to the lens within the wide autofocus frame. If you chose the spot focus it will focus on a smaller area in the center of the image. That gives you more control over precisely what it is that is focused on.
I think the AiAF was desgned to help newbies when they took portraits of two people and the older AF systems would focus on a distant object BETWEEN the two people, putting the two people out of focus. The AiAF frame brackets are about twice as wide as other frames, and will hopefully focus on at least one of the two persons.
