I currently have a 32 GB with 3G on pre-order, but I am wondering if I should up grade to the 64GB. I'm going to use my iPad mostly for surfing and running apps. I doubt that I will ever load a video on it, or music. I may load a few pictures, but not much. I have about 40 apps that I want to load, a few (4 or 5) which are games. To those lucky enough to have an iPad, how much space are you using?
