I have done some testing around this (motion blur while scrolling) and can confirm that motion blur is not practical for scrolling. It “looks nice” and is a nice effect, but makes the text completely unreadable while scrolling.
If you have access to a Mac, the easiest way to check for your self is to add a CI motion blue filter to a tableview’s layer’s filter property (you can change the strength of the blur based on the speed of scrolling if you would like).
