Are you really as stupid as you are coming across? There is NOTHING INHERENTLY SUPERIOR ABOUT YOUR WINDOW BOXES. These scientist and engineers are not choosing Macs because they make great "terminals", any more than they choose a Windows machine for that purpose. If that were the case, they'd choose the cheapest "terminal" computer they could. These engineers chose Macs for good serious reasons. Contrary to your asinine claims which you stated were based on hearsay. Do you even know what UNIX is, or what it is capable of?
Just a word of advice.
"No".
They chose those macs because they got a great deal from apple for some fancy displays. NONE of the graphicboxen you refer to were actually involved in any way with any actual real-world activities. I should know. I was at the AMES Research Center when the first Mars Lander photos came in.
But, feel free to believe that those machines (laptops) were doing something grand. I would be the last to take away such a momentous occasion from you...
