I've got a Netbook setup as a datalogger in my car with RaceChrono putting together the GPS and OBDII data, figured I'd share a video from this past weekend with other RaceChrono users:
The reason I'm going with the CarPC setup is I'm making OBDII and GPS location information available data available to the web thanks to a software agent and 3G connection. Real time video/audio to it is fun.
I currently use an iPad to control the Netbook, it just connects to the netbook via wifi thanks to a Cisco router under my seat.
I just sent in my donation - thanks RaceChrono! I'd love a command-line ability to drive the the Windows app now ;)
