I don't have any trouble with storage on my 16g WiFi. I keep most of my items on my iPhone 4 or my iMac. I just put a movie on my iPad 2 if I want to watch it instead of on the TV or iMac. I keep my audio books on iPhone 4 also as I plug it in and listen to podcasts and books in the car. As Zig Ziglar calls it Automobile University. I just don't try to load everything on my iPad 2. Have DropBox, so everything works fine for me.
