A new location-aware GPS-CS1 camera device from Sony, for about £100. A Digit review says the device comes with Microsoft GPS Image Tracker 1.0, and thus…

Basically, it tells you at which spot on the earth a photo was taken. It’s not perfect; about +/- 40 feet. As well as offering an added level of ease and precision to content-creation for mobile and tour services, I can also see the potential for interfacing this with mapping services to automatically slot photos into a template for a unique print-on-demand guide book, thus making a paper book that you can carry to the sort of places where you want to be as low-tech as possible due to the risk of crime.
