I noticed in news coverage this evening that Vindigo had closed up shop. I first ran into them when the agency that I worked for launched their London guide. The software ran on Palm PDAs in glorious monochrome.
In terms of functionality the software provided recommendations on restaurants, clubs and bars (the play section in the picture), and shopping. It also had maps that provided point-to-point directions and was updated by syncing via serial port or USB connected cradle.
This was back in 2000, way before Google Mobile and GPS chips in everything. Palm was still a respectable technology company and the internet was going to change everyone’s lives but we just weren’t sure about the business model yet.
Ignoring the personal information management software that comes as standard on a Palm for the moment, AvantGo (a kind of pre-RSS mobile newsreader) and Vindigo were the essential software that I carried on my PDA.
