The tourists, a skier and snowboarder, were lost in the mountains of Southeast Switzerland, with temperatures reaching -15 degrees Celsius. They attempted to phone for help, but their mobile phone ran out of juice just after making the connection. Luckily, the faint light of an iPod screen was enough to catch the eye of a helicopter rescue team, who recovered the two sports enthusiasts quickly enough to avoid any more serious consequences than very mild hypothermia.

Reuters reported this story, but didn't go into the kind of detail that techies like you and I really need. What kind of iPod was it? What generation? What brightness setting was the backlight set to? Is there a difference in helicopter visibility between, say, LCD and OLED? Without that kind of information, I don't know that I can ever go skiing in remote Swiss mountains again. [Reuters]
