"Federal agents at the border do not need any reason to search through travelers' laptops, cell phones or digital cameras for evidence of crimes, a federal appeals court ruled Monday, extending the government's power to look through belongings like suitcases at the border to electronics."
"... travelers should be aware that anything on their mobile devices can be searched by government agents, who may also seize the devices and keep them for weeks or months."

Digital cameras with pictures of bonus locations, laptops for route planning, cellphones as backup digital cameras, GPSes with route information, MP3 players for musical diversion. What fun.
