Sony HDR-XR520V

Shoot first and ask questions—like “Where am I?”—later. Sony’s camcorder is the first with a built-in GPS chip, which lets it tag each video clip with the location where you hit “record.” Sony developed its own computer software to read these tags and categorize your films according to place, since video-sharing sites like YouTube don’t yet have a standard for reading geotags from files (the way many photo sites do). Bonuses for travelers: The screen can display maps to help you get your bearings, and the camera automatically adjusts the time and date stamp depending on your whereabouts.
