So i traded a bunch of books in at Powells', and got store credit, thinking there were some Aperture 3 books out. Nope. This is interesting, as they had CS4 books out by the time the program launched. So is it worth it to buy an Aperture 2 book (I am sure some things apply)? I looked at amazon and found one result, and it was a pre-order for September.. I also didn't see any LR3 books. I looked just to see if it was just A3 that didnt have any books, but it was both..
