My wife wants an in-car/portable DVD player to keep the kids amused. I started thinking that perhaps a notebook could do double duty. Has anybody investigated this? What I would need is a light laptop that could fold the screen flat (180 degrees) and had good battery life 3 hrs +. Ideally, i'd like a sling to go over the seat so the laptop screen could be falt against the back of the seat. But if it was hideously expensive, then that would not be viable either as I could buy a cheaper laptop and a portable DVD player. Is it possible? Any suggestions?
