Anyone who killed themselves over an iPod deserves the utmost ridicule, period. I wouldn't even be afraid of being haunted by his ghost.
If you believe in conventional ethereal logic, it dictates that ghosts and specifically more powerful ghosts are left behind by people who are intelligent, wise or generally have a lot going on upstairs.
This kid killed himself over an iPod. An iPOD, FFS! How powerful could his ghost POSSIBLY be?
