We were just kidding around and mincing words...
PS Elements is basically a simplified version of CS. It's like comparing Windows XP Pro and Home versions. The latest Elements v5.0 has a lot of functions similar to CS2, curves being one of them. I've tried v5.0 but am sticking to v3.0 because I'm already so used to the interface, layout and functions and I can work more effieicntly that way.
I don't like to spend too much time post processing although I know it can really help to bring life to an image that would otherwise be considered an "acceptable snapshot".
But for hobbyist like me, price is an important factor and case in point, Elements is almost half the price of CS. ;p
