Touch screen would be really sweet. I have used a laptop in the truck and it is pretty much impossible to do anything while you're driving. I've always had a passenger along to struggle with the laptop while bobbling down the interstate.
So, with a touch screen...
Could you eliminate the need for a car stereo?

I'll tell ya where I'm really going with this. At some point in the future i'll be building a dash for the crew cab. I'll also be building the console and possibly an overhead console.
I was considering the value of pulling the components from a computer(or buying specific pieces) and building them into the console or dash or both and having a built in on board computer.
I just don't know if its worth the hassle. Maybe someday the crew cab would be fuel injected and could take more advantage of it. At the same time, maybe it'll be a CTD rather than a gasser.
