I have always thought the next evolution of the ipad wold be that it snaps into the center console of a car and wham you have your music, nav, phone (cell signal needed) ect. all in one device.
Same here. Makes no sense anymore to pay for a crappy overpriced computer in your dash when we've all already got them in our pockets.
I know that Apple is working on automotive products. Hope it's something along these lines.
