In response to keypresses, it doesn't bother me too much, as I'm used to the Windows-style behaviour of PgUp/PgDn/etc. moving the caret, much as the Mac behaviour of not doing that is sometimes useful. But for mouse wheel scrolling, which I do a lot - precisely because on Windows this typically does not move the caret! - having point follow along has never felt right.
Iam pretty sure you can customzize that if you want.

In emacs the cursor would be somewhere around line 600 instead.
