So I always get 32GB iPhones, but they are half the price of the iPads. I just ordered a 16GB iPad, and now i kind of have buyers remorse. i feel like I should have gone 32GB. But with AppleCare - it came out to $640. This is my first iPad, so what I am really looking for is advice from individuals with either the 16GB or the 32GB. Is it that big of a difference? Is16GB enough???
