Alternative Suggestion (Score 1)

Skip the DVD backups and carry some larger memory keys, they're nearly indestructible and light. You can purchase them in most airports. DVD burners are prone to dust, dirt, breakage etc. Also, you have to carry media, then try to mail it without damage. I'd suggest for thin and light a EEE PC, 7" screen, solid state hard drive, cheap to replace. Get a light aluminum hard shell and you're good to go. I've traveled with a 14", 13" and 10" laptop. By far, the smallest laptop was the best for weight and ease of use. Just check to see if you are able type on such a small keyboard. Upgrade the ram to a couple gigs and load XP, if that's what your familiar with. The base operating system is a type of Linux and is pretty good. http://eeepc.asus.com/global/product.htm
