Whnever I've owned an Apple notebook it's only really ever stayed in my room, I never really take it anywhere out the house. But I'm going traveling for a year and just wondering how people's Airs have held up with taking them to college, travelling with business etc. Are they pretty durable to be threw in and out of backpacks and stuff like that? I'm always scared of breaking my MacBook but I think I might be being over the top. Thanks.
