Hello, I'm thinking about getting an iPad, but 64GB is WAY too small for the amount of videos I want to put on it (I'm a student with just that amount in science and math videos alone). I recently swapped out my MBP HDD (160GB) for a 500GB HDD and the cases were the same form factor. I'm assuming that the same would probably be true for the iPad(?). If I could get confirmation from somebody that they had successfully installed a larger HDD in their iPad, that might make me more willing to buy one. Any feedback would be helpful. Thanks, J.
