This cradle seems like a good way of running an Entertaiment System in your Car or MPV. You will get a very wide screen as average laptops screens are arround 14″ to 15″
This cradle will hold the laptop firmly and it will only cost you USD25 to for the entertainment system in your car.
I guess you need to buy some speakers too….or you can get some FM transmiter and tune your radio to the correct frequency.
