Cars already have an on-board computer, but what we wanted was an embedded computer, an actual PC with an LCD touch-screen that we could shove under the seat. We wanted it to be nice looking but also to perform well for the driver when it comes to playing music and other multi-media.

I've had my 'check engine' light come on many times over the years as have most people, and usually your car keeps running fine and you're wondering what to do. Then you bring it to the mechanic, they hook it up to their diagnostic computer and you find out it was a fluke; some sensor went bad and the light came on.
