Uh oh, maybe I should have ordered the 32 GB.
I was torn between 16 and 32 GB, eventually I went for the 32. I looked on Ebay and noticed that 32 GB iPad 2 is selling on average for $70 more than the 16 GB, so I figured even if I don't need the extra storage (I am more of a streamer than storer, is that a word?), I can recoup most of my $100 investment when the 4th or 5th generation iPad appears.
