A Paris iPad app - oui!

DK Publishing's Eyewitness Travel Guides set the standard for visually oriented guidebooks, so it's the perfect match for the iPad's high-resolution display and intuitive design.

The first app in a series, Eyewitness Travel: Paris, isn't cheap ($17), but promises to be the only guide you need before visiting the City of Light. It can take you on 14 beautifully illustrated walks, inside 17 landmarks and along a historical timeline. It also has over 400 photos.

Everything comes together in the Area by Area section. Call up the Latin Quarter and toggle between hotel and restaurant listings; or explore a map studded with 11 places of interest, then click to see nearby lodging, eating and shopping options. You can also locate yourself on the GPS-enabled map and start finding your way around in real space.
