32GB, because you can never increase the internal space and you will always have more you want on it than you can carry with a 16GB version. I am looking to get a N7 32GB this weekend, so how much actual space do we get?
it looks like its about 29ish gbs, plus you can use an OTG cable with a flash drive to view movies and songs etc. thats still pretty good depending on the uses for it
