Not really, it has saved my 9100 from dust, water and severe vibration many times. Do you use your lappy in a Helicopter in the middle of a desert or a snowfield or at tropical rain forest? Not overkill at all my friend.
Im not a fan of LOTR but those are some nice and funny pics you have there...I was like "what the hell? Theres helicopter in LOTR?!" that is what got me interested in reading this thread. Those are the helicopter you guys use rite?
