Sound on screen refresh?
Am I the only person who can hear a very faint sort of rattling/sandy noise behind the screen whenever it refreshes? Turning a page, new menu, etc... It's really not loud. It's noticeable however, and my main concern is that it bespeaks some mechanical glitch. My iLiad never does this and never did. (My subsidiary fear is that even so faint, it'll become annoying... but then I'm neurotic.)
