I forgot to post this way back, but Burt Rutan built a plane a few years back called a Boomerang, the brains of the plane are a pre G3 laptop. I am on the company dull laptop in Boston so don't know how to post the geewhiz pix, but here is a link to a cockpit shot with the apple laptop. Boomerang . I remembered this while discussing the recent sub that ran into a sea mount. Then discussing the brit sub running on windows, or I guess gets towed with a blue screen of death any way. But apple laptops running complex aircraft is cool!
