Never mind, I'll wait a year and probably be able to pick up something exactly as I described. Replace my car iPod and my GPS with one device. I suppose I could do this right now with an iPad but I'd have to pay for the 3G to get google maps -- I'd rather have internal maps.
If you're going to mount it in a car, just plug in a USB GPS.
I'm skipping this one as a car computer because I bet the screen is junk and the memory is awfully small. In a year there should be a bunch of good ones to choose from.
No you wouldn't. You'd have to buy the 3G version to get the GPS censor, but there are plenty of apps available that store your maps on the iPad. I'm pretty sure the GPS censor works fine without a 3G plan...
It's kind of crazy you can't buy a discreet touch screen this size for less than twice the price.
