With experience around the iPad (both generations) and the Kindle Fire I found outside of games the kids were having way too much fun making videos. Adults tended towards pictures but kids tended toward videos, many about tormenting each other. Which mean the old iPad and Fire sat relatively unused - there were like "if I have too".
I do like the size of seven inch tablets, its easier to one hand use them while reading at the table and eating, like a modern day paper. You would be surprised how ungainly feeling the larger iPad feels being used this way. The Fire became my table reader simply because of its form factor.
