Do you want a Dash GPS ? We are going to give one away to the person who can come up with the best idea for a geo-aware app that would work on the device. (Courtesy of Trulia and Dash ). The Dash is a GPS unit that is connected to the Internet through a cellular data network so it can tell you where is the nearest restaurant, gas station or hospital. You can also download geo-RSS feeds and apps that tell you where is the nearest WiFi network or winery. In May, the startup opened up its API to outside developers. Some apps that have been created for the Dash include Trulia's real estate search (handy when home hunting in the car), weather updates from WeatherBug, nearby speed traps from Trapster, geo-tagged Wikipedia articles, and you can even Twitter from your Dash (not while driving, please).
