Amazon Prime Air?!?

This is sooo crazy and so cool! You have to check this out!  Amazon is introducing a new concept of delivering packages to people in less than 30 minutes of when the order is placed... sounds crazy?  By using a small helicopter device to carry packages to your door, Amazon is upping their game in the online consumer world.  I can see how there would be MANY complications with this kind of system, but I think it could happen in years to come.  What do you think?
