Not a bad strategy! I had similar paranoia during an Australia trip, and ended up bringing an iPad and a portable keyboard instead of a laptop. This was in 2010 so iPad software wasn't nearly as supportive of keyboard input. It worked okay until I tried to plan the next day's riding using Google Maps. :/
