The networked in-car GPS system, Dash Express, is finally available, dealing a blow to road safety everywhere. Central to the wonderful distractions of this open-source dashboard computer is the two-way internet connection, which allows the sat-nav part to offer live updates based on known traffic trouble spots and current traffic conditions.
The WiFi and GPRS connections also mean you can send information (destination addresses and the like) direct to the Dash from any PC, and Yahoo's Local Search gives drivers one less reason to stop and ask for directions. All it needs is YouTube so you can Rickroll your passengers.
The Dash is $400, and monthly plans start at $10. Maybe not the cheapest option, but it's possibly one of the most flexible, and the over-the-air software updates mean it should keep getting better.
