HI, I was wondering what kind of experiences people have had with the need to remove their powerbook from their case or sleeve before placing the PB through the airport x-ray machine. I would be happyer if I did not have to remove the bare powerbook everytime and subject it to potential abuse and scratchs. Anyone forced to remove a PB from sleeves like the Crumpler School Hymn or the Zero shock from Shinza? Will they at least allow you to leave the PB in a microfiber sleeve like the PowerSleevs? Any succes leaving it in a more substantial sleeve like the Tom Bihn, AcmeMade, or Timbuk2? Any experiences would be welcome!
