I think it really depends on what you are doing on it. If you are reading books or the newspaper it seems to last forever. If you are watching videos or playing games, the charge seems to run down faster. If you do a variety of things it just keeps going and going and going...
I think so too.
Is there a car charger for the ipad, does anyone know?
Yes, made by Griffin. Here it is at Amazon. I picked mine up at an Apple Store.

On the battery life:
I ran mine completely out, at 21% left I started a movie and let it run. It played about 1hr 30m of a movie before it auto shut down. If I had started at 30% it would have played the whole thing. Which is great because I don't know of any other video player that would play an entire movie with just 30% left on the battery and I have a bunch of different ones.
Oh great!! Thank you so much!
