Car Computer - Dreams for the Future!

I have been imagining my vehicle having a car computer. And this is the display I think I could afford! It is a VGA touchscreen, and I can imagine it hooked up to a crummy laptop I have (a IBM Thinkpad 600E).

It even has 5 inputs: one computer (VGA), two video composite, one S-video and one audio input(RCA) inputs one of which could be used for rear view cameras!

The contrast ratio sounds crummy at 200:1 and I am pretty sure it sucks in other ways but it does sound nifty!
