The main question I have is... how easy would it be to use this laptop as a carputer.
Acer Aspire One
I would get an external DVD writer through USB and the usual.
For sound to the car speakers, would it be best to use an external sound card? I have two 4x4s and two 6x9s in the truck that I would prefer to use, and the head unit I have will find its way to another vehicle.
Also, what would be the best way to power this from the vehicles battery?
