What tech to backpack around the world with?

ryrw writes: I'm planning to spend a year backpacking around the world and the hardest question I have to answer is: What technology do I take with me? Aside from the obvious (digital camera, ipod, et. al.) what technological devices would you you take? Specifically, I wonder if I should bring my nice and shiny MacBook Pro. I can think of lots of uses for it (offloading pix, updating blog, email, etc.), but I'm worried it will be lost or stolen along the way. Does anyone have experience with travel while toting technology?
