My roommate has the same exact TiBook that I have, but his has been experiencing some disturbing screen anomalies...static, scan lines, flickers, and a just generally jumbled up display. This occurs upon his moving of the hinges...say when readjusting the angle. Moving it to just the right angle allows a normal display. One girl in class even asked "hey, is that your screensaver?" If you look closely, you might make out an InDesign palette.
