Ok, first post here. I know there is a search, but I'm hoping this is the best and more direct way to get some answers. I have a 16GB iPad 2. I went the 16GB route thinking there would be an alternative to adding storage. I will be taking a trip upcoming, and now I'm looking for the best way to achieve this. I will primarily being using this for music and movies. I don't really use the iPad for files or documents. So is Airstash the best and cheapest way to go? Is 64GB really the maximum SD card that you can use? Are you able to charge it off the iPad or are there any car chargers for it? Are there any better options that would work that would cost around the same $100 that the Airstash costs? Thanks for any advice and answers.
