for what you think you want it for, 16gb is fine but beware....you may well find that once you have got it, you want to use it for other things and wish you had gone for more memory. Just like computers, tablets not only change how we do things, they change what we do. I had a 16gb ipad1 and started collecting books on it and some fairly big, useful apps, like starmap and shipfinder, a few art ones, and so on. I won't say that i quickly filled it but I did fill it so when i upgraded to a mini I went for the 64gb.
