I will be traveling from Europe to Australia this summer to visit relatives. I am planning to take my MacBook Pro with me, however as I've never been abroad before, I am not quite sure if it's safe to bring an expensive piece of electronics with you and on plane. Should I rely on my smartphone instead for communication (email, skyping, IM) and leave MBP at home? Is there a significant danger of bumping it into something when in flight or at the airport so that it breaks, or maybe the customs officer will destroy it if he/she doesn't want it to be within Australia's borders or suspects I might have hidden porn on it? Do any of you travel with your expensive electronics and how do you handle the perils of the road?
