I'm having trouble deciding how much memory I will need. Since the iPad will be my travel companion I plan to have at least 50 books, 300 songs, 1,000 pictures, 20 films, 10 games, 20 applications, couple of newspaper subscriptions. I am not sure if the iPad will support HD films, will that eat up my memory, does 3G also use up memory? I was leaning towards the 32gb model but I am not sure if it is too much or not enough. How is everyone else deciding how much memory they need?
