Well since i came here in last 2-3 months i'll chime in.
Ive been wanting to put a computer in my car for a while. Never really gave it serious thought till i actually had some money to throw into a decent audio system. So after shopping around looking at mp3 cd players, changers, Fatbox and other hard drive based music kegs i came to the conclusion none of them did everything i wanted. Basicly i wanted something like Kenwood Music Keg but i wanted it to have wi-fi so i wouldnt have to keep taking the drive out and into the house to put music on it. Then i found this thing called Omni-Fi that did exactly this, but the damn release date kept getting pushed back month after month so i said the hell with it. Im putting a full computer in my car and be done with it. Did a LOT of searching the net to get info on the best way to do it, and when I found this site all my searching stopped. And now I got my 7in LCD touch screen carputer up and operationaly for about 2 days now and i am LOVING it.
