If you were relying on that map, I wouldn't suggest relying on the cached image of the map on the ipod touch... I'm not sure how you would save them on the ipod touch for later viewing, but that's what you would need to do. and if you wanted to zoom and pan and whatnot after you leave the wireless network, you would need those zoomed images saved as well. Too bad NASA Worldwind isn't mac/ipod touch compatible, it does a better job of caching the images in my experience.
but I know we can't all stay here forever, so I wanna write my words on the face of today...
