Hmmm... while I'm not panicking. I am concerned with just how much I will be able to keep on my iPad. I bought a 32GB after changing my mind on the 16GB. After the order was processing, I thought about calling and switching to the 64GB, but with it being my first ever iPad, I figured 32GB should be enough.
Now, with the last few posts concerning books, I have to ask just how large are typical book files? I mainly like to read for my own enjoyment. However, I also read to learn a subject from time to time and during those times, can easily cross reference information between 3-5 books. One of the lures for me with the iPad was to be able to "flip through" the different books without having so many physical books surrounding me. But with 2GB files for just a few chapters? Maybe that won't be happening.
If this is just for one particular app or certain books, then ok. Otherwise...
