How feasible would it be to use an iPad as a GPS in your car?
A regular portable GPS just needs the windshield to locate the satellites while the iPad requires AT&T 3G.

I am wondering how accurate it would be and how often you would hit dead spots in AT&T service.

Any thoughts?

I would assume it would be very similar to an iPhone. I've used MotionX GPS on my iPhone a bit around my area. Worked great, but my use was limited.
