I just don't associate electronics with survival gear. For the military, where they are in a bounded area of conflict with backup, sure, electronics are good. But when an EMP takes the power out everywhere, or when the zombies come, this thing would be useless. Spend your $300 on ammo instead.

FWIW, I also checked out this thread to find out about the newest dietary supplement! I guess that goes to further illustrate my bias that electronics (tablets) != survival gear.
