"I'm leaning towards the ethernet cable for security reasons"

In this day and age does that really make you any safer?  If someone really wants to hack into your system, they will hack into their system.  It sucks that there are so many slime balls out in the world that everybody has to live in fear of being hacked.  Maybe they need to start tracking a few of these people down and start making examples of them.  Maybe cutting off a hand or arm of a few might get the attention of the other vermin out there.
