I've been struggling over the last few days over whether to buy a 16GB or 32GB iPad 2. I've done a bit of Googling and all I keep seeing is people saying the same old "if you don't put a lot of music or video on it then it'll be fine". That's fair enough, but I knew that before I did the search, and I can't say for sure exactly what I'll do with my iPad once I get it. So, my question to owners of 16GB iPads is: Is it enough? Do you wish you'd bought a bigger one? What do you use your iPad for?
