IPhone :: IPad In The Car Or Other Good Uses For It

If i had the money to buy an iPad id want to put it into my dashboard of my car. That would have been a better idea for apple to market the iPad. That way you can have a music player, gps, maps, watch videos, not sure what else but on a big screen like that in the car would be nice. I think iphone and ipod touch are too small to use in the car. I dont know why apple didnt think of doing this in the first place. Be able to put it and detatch it from the dashboard cuz you wouldnt wanna leave it in the car. Another good thing to use it as would be like an mpc with intua beatmaker app if you make music. It would be way cheaper than buying an mpc. What would be some other good uses for it?
