I am looking to do a carputer with Android as the OS. It is a native touchscreen OS so that should make integration a little easier.
For the main CPU I will either be using a netbook or a notebook, as they have batteries which makes standby easier to deal with. I have a Lilliput 7" flip out touchscreen to use as a head unit and will be getting a small amp to power the 4 speakers in my car. I am not looking for anything too fancy, but something that I can use more for work. I am a network admin for a large bookseller that sells on multiple websites and has 3 B&M locations that I travel between on a regular basis. My solution for internet connectivity will be wifi tethering from my Android based phone (Evo 4G is the next purchase on my list.)
Thanks again guys for any advice or insights you can give. I actually have an Android ISO for use in a PC environment that I will be working from.
