This should go without saying, but don't drop this tablet...
Mine fell from a height of about 3 feet. Nothing wrong at first, until I needed to recharge, and found that whatever piece was inside to accept the power adapter was not there.
I was wondering what was rattling around inside...
seriously, only like $250 for an extra 16 gb!!!
BTW, you can get 16GB of expandable memory for like $16 bucks, but why would you?
