Well, it was bound to happen. Given that the Mac mini's front dimensions are 2" x 6.5", and a car stereo port is 2" x 7", it was inevitable someone would want to put the former into the latter. I'm not quite sure I get it myself - yes it would be nice having iTunes as your car stereo, but the mini seems overkill for that and if you used an iPod instead it could leave the car with you. But then again I don't have kids - I guess parents would appreciate the DVD-playing ability of the mini. I suppose with an internet-capable mobile phone you could also do email in your car, although I can't think who would want to. The voice control aspects of having a full-fledged Mac in the car are interesting, but to be frank my own experiences with voice recognition don't fill me with eager anticipation. I also wonder about the power supply. Will the mini get turned off when you aren't using the car? If it does I wonder if they've taken the Mac's relatively slow startup into account, presumably you'll just have to wait a minute or two after turning on your engine in order to play some music.
