I am considering purchasing a Macbook to replace my Pismo (great machine). When I am at work, I would have the Macbook on an iCurve. At work my Pismo is attached to a mobile LCD projector. Does the Mini DVI port have enough integrity to withstand the force of the adapter and a VGA cable hanging from it to the floor when the computer is resting on the iCurve? I just wondered since the Mini DVI does not have the thumb screws like the DVI or VGA ports.
