On average, how much space do applications take up? I know some applications are smaller than others, and a lot of them use cloud storage, but surely there are some apps that use local client storage. I am basically trying to determine whether a 16GB or 32GB iPad 2 is the way to go. I won't be putting my entire music library on it, nor do I plan on having a ton of movies or TV shows, which I know would eat up a majority of local storage. Thanks for any information.
