Basic idea: a personal digital assistant that helps me to navigative unfamiliar real-world places. <name> would be a non-invasive stream-of-consciousness type support service.

Input and training: <name> builds up a profile of what I like and where I buy it from.

Output/benefit: when walking around in an unfamiliar place (such as a foreign city), <name> uses GPS and contextual information about my surroundings to highlight relevant services. The advice is then piped to me via a bluetooth headset.
