Gallery: 10 useful Android apps

This is a travel guide app with a twist: it'll let you impress your friends with your ability to correctly identify prominent landmarks on the horizon (provided they don't see you reading the description as you hold your phone up to said landmark... ). The feature works by making use of GPS and the G1's embedded compass to pinpoint landmarks as you view them via the device's camera, then mashing the location data up with info from Panoramio, Qype and Wikipedia to correctly identify them and provide additional details. The result is what the developers describe as an "augmented reality view".
