yea it's cool and all but how many computers are going to respond postivily to all the animation features. My first gen macbook didn't display itunes coverflow seemlessly. i mean some of it seems like fluff anyway, i mean who 'needs' the reflection of the window on the dock?
CoverFlow has never been smooth, it is quite buggy. Maybe in Leopard it would be OK.
Your MB is capable of handling coverflow.
