I have an XO laptop from the One Laptop per Child program. I haven't travelled the world with it yet, but I can tell you it is perfectly capable of being a lightweight machine for internet browsing and writing. Its specs allow for toleration of extreme environments and voltages for charging. I can charge mine in the car. The battery lasts me about 3 hours, or more if I dial down the backlight and turn off the wifi. The screen really is sunlight-readable. Another comment talked about storing photos on an SD card. That could work since the laptop has an SD slot and three USB ports. Of course you would have to see if the OS would work with your camera. The machine itself weighs about three pounds and is smaller than an 8.5x11 inch piece of paper and just a little thicker than a US quarter is in diameter. Caveat: the keyboard is small for adult-size fingers. Some custom installation is needed to get things like Flash websites to work. Oh, and you'll have to get one off Ebay unless you have some helpful contact since they are not being sold singly at present.
