Completely filling the device with long documents containing random characters, before the reset, would make an forensic examination almost impossible. To make it completely impossible, you'd probably have to run the delete program on a different computer (Fire = computer) than the one whose data is being deleted off of.

If anyone is that worried about it, physical destruction is the only sure way. That's what the company I work for does with all failed and discarded hard disks. They get crushed.
For the requirements of most people who simply want to ensure that their address book is not immediately visible to the next purchaser, a factory reset is entirely adequate.
