Stuck on Earth is a tremendous iPad App for photographers and travelers alike, which will allow you to see interesting places through the eyes of great photographers. It's absolutely free, and I see this as a great way to scout out locations when traveling abroad. I have a feeling this will become one of my most favorite apps. One note: Make sure you have a very fast wifi connection as it takes time to download images, if you dont have it the experience is diminished.
