The problem with scrolling in Lion is not so much that it's "new stuff" but rather that it breaks a convention that people (even Apple users) have been used to for decades. All of a sudden, by moving your pointer down, you scroll up. It is freaking annoying.

I don't know, I don't like most of the changes in Lion. They look like a really bad "first step" towards something that isn't there yet. Like removing your car's wheels just because you imagine that at some point people will want flying cars that work on antigravity. And then you get the inconsistent bits like making the window buttons smaller. Just... crap.
